Release Note (0.40.0)

Release time: 2023-12-22 12:12:15

This release contains 1 new feature, 3 bug fixes and 2 documentation improvements.

🆕 Features

Add Epsilla connector (#1835)

We have integrated Epsilla into DocArray.

Here's a simple example of how to use it:

import numpy as np
from docarray import BaseDoc
from docarray.index import EpsillaDocumentIndex
from docarray.typing import NdArray
from pydantic import Field


class MyDoc(BaseDoc):
    text: str
    embedding: NdArray[10] = Field(is_embedding=True)

docs = [MyDoc(text=f'text {i}', embedding=np.random.rand(10)) for i in range(10)]
query = np.random.rand(10)
db = EpsillaDocumentIndex[MyDoc]()
db.index(docs)
results = db.find(query, limit=10)

In this example, we create a document class with both textual and numeric data. Then, we initialize an Epsilla-backed document index and use it to index our documents. Finally, we perform a search query.

🐞 Bug Fixes

Fixed type hints error in Python 3.12 (#1840)

DocArray type-hinting is now available for Python 3.12.

Fix issue serializing and deserializing complex schemas (#1836)

There was an issue when serializing and deserializing protobuf documents with nested documents in dictionaries and other complex structures.

Fix storage issue in TorchTensor class (#1833)

There was a bug when deep-copying a TorchTensor object its dtype was not float32. This has now been fixed.

📗 Documentation Improvements

• Add Epsilla integration guide (docs(epsilla): add epsilla integration guide #1838)
• Fix sign commit command in docs (docs: fix sign commit commad in docs #1834)

Release Note (0.39.1)

Release time: 2023-10-23 08:56:38

This release contains 2 bug fixes.

🐞 Bug Fixes

From_dataframe with numpy==1.26.1 (#1823)

A recent update to numpy has changed some of the versioning semantics, breaking DocArray's from_dataframe() method in some cases where the dataframe contains a numpy array. This has now been now fixed.

class MyDoc(BaseDoc):
    embedding: NdArray
    text: str

da = DocVec[MyDoc](
    [
        MyDoc(
            embedding=[1, 2, 3, 4],
            text='hello',
        ),
        MyDoc(
            embedding=[5, 6, 7, 8],
            text='world',
        ),
    ],
    tensor_type=NdArray,
)
df_da = da.to_dataframe()
# This broke before and is now fixed
da2 = DocVec[MyDoc].from_dataframe(df_da, tensor_type=NdArray)

Type handling in python 3.9 (#1823)

Starting with Python 3.9, Optional.__args__ is not always available, leading to some compatibility problems. This has been fixed by using the typing.get_args helper.

Release Note (0.39.0)

Release time: 2023-10-02 13:06:02

This release contains 4 new features, 8 bug fixes, and 7 documentation improvements.

🆕 Features

Support for Pydantic v2 🚀 (#1652)

The biggest feature of this release is full support for Pydantic v2! We are continuing to support Pydantic v1 at the same time.

If you use Pydantic v2, you will need to adapt your DocArray code to the new Pydantic API. Check out their migration guide here.

Pydantic v2 has its core written in Rust and provides significant performance improvements to DocArray: JSON serialization is 240% faster and validation of BaseDoc and DocList with non-native types like TorchTensor is 20% faster.

Add BaseDocWithoutId (#1803)

A BaseDoc by default includes an id field. This can be problematic if you want to build an API that requires a model without this ID field. Therefore, we now provide a BaseDocWithoutId which is, as its name suggests, is BaseDoc without the ID field.

Please use this Document with caution, BaseDoc is still the base class to use unless you specifically need to remove the ID.

⚠️ BaseDocWithoutId is not compatible with DocIndex or any feature requiring a vector database. This is because DocIndex needs the id field to store and retrieve documents.

💣 Breaking change

Remove Jina AI cloud push/pull (#1791)

Jina AI Cloud is being discontinued. Therefore, we are removing the push/pull feature related to Jina AI cloud.

🐞 Bug Fixes

Fix DocList subscription error

DocList can be typed from BaseDoc using the following syntax DocList[MyDoc]().

In this release, we have fixed a bug that allowed users to specify the type of a DocList multiple times

Doing DocList[MyDoc1][MyDoc2] won't work anymore (#1800)

We also fixed a bug that caused a silent failure when users passed DocList the wrong type, for example DocList[doc()]. (#1794)

Milvus connection parameter missing (#1802)

We fixed a small bug that incorrectly set the port of the Milvus client.

Release Note (0.38.0)

Release time: 2023-09-07 13:40:16

This release contains 3 bug fixes and 4 documentation improvements, including 1 breaking change.

💥 Breaking Changes

Changes to the return type of DocList.to_json() and DocVec.to_json()

In order to make the to_json method consistent across different classes, we changed its return type in DocList and DocVec to str.
This means that, if you use this method in your application, make sure to update your codebase to expect str instead of bytes.

🐞 Bug Fixes

Make DocList.to_json() and DocVec.to_json() return str instead of bytes (#1769)

This release changes the return type of the methods DocList.to_json() and DocVec.to_json() in order to be consistent with BaseDoc .to_json() and other pydantic models. After this release, these methods will return str type data instead of bytes.
💥 Since the return type is changed, this is considered a breaking change.

Casting in reduce before appending (#1758)

This release introduces type casting internally in the reduce helper function, casting its inputs before appending them to the final result. This will make it possible to reduce documents whose schemas are compatible but not exactly the same.

Skip doc attributes in __annotations__ but not in __fields__ (#1777)

This release fixes an issue in the create_pure_python_type_model helper function. Starting with this release, only attributes in the class __fields__ will be considered during type creation.
The previous behavior broke applications when users introduced a ClassVar in an input class:

class MyDoc(BaseDoc):
    endpoint: ClassVar[str] = "my_endpoint"
    input_test: str = ""

    field_info = model.__fields__[field_name].field_info
KeyError: 'endpoint'

Kudos to @NarekA for raising the issue and contributing a fix in the Jina project, which was ported in DocArray.

📗 Documentation Improvements

• Explain how to set Document config (#1773)
• Add workaround for torch compile (#1754)
• Add note about pickling dynamically created Doc class (#1763)

Release Note v0.37.1

This release contains 4 bug fixes and 1 Documentation improvement.

🐞 Bug Fixes

Relax the schema check in update mixin (#1755)

The previous schema check in the UpdateMixin was strict and does not allow updating in cases the schema of both documents are similar but do not have the same reference.
For instance, if the schemas are dynamically generated but have the same fields and field types, the check will still evaluate to False and it would not be possible to update the documents.
This release relaxes the check and allows checking whether the fields of the schemas are similar instead.

Fix non-class type fields (#1752)

We fixed an issue where non-class type fields used in schemas with QdrantDocumentIndex result in a TypeError.
The issue has been resolved by replacing the usage of issubclass with safe_issubclass in the QdrantDocumentIndex implementation.

Fix dynamic class creation with doubly nested schemas (#1747)

The following case used to result in a KeyError:

from docarray import BaseDoc
from docarray.utils.create_dynamic_doc_class import create_base_doc_from_schema

class Nested2(BaseDoc):
    value: str

class Nested1(BaseDoc):
    nested: Nested2

class RootDoc(BaseDoc):
    nested: Nested1

new_my_doc_cls = create_base_doc_from_schema(RootDoc.schema(), 'RootDoc')

We fixed this issue by changigng create_base_doc_from_schema such that global definitions of nested schemas are propagated during recursive calls.

Fix readme test (#1746)

Release time: 2023-08-03 03:11:16

This release contains 6 new features, 5 bug fixes, 1 performance improvement and 1 documentation improvement.

🆕 Features

Milvus Integration (#1681)

Leverage the power of Milvus in your DocArray project with this latest integration. Here's a simple usage example:

import numpy as np
from docarray import BaseDoc
from docarray.index import MilvusDocumentIndex
from docarray.typing import NdArray
from pydantic import Field


class MyDoc(BaseDoc):
    text: str
    embedding: NdArray[10] = Field(is_embedding=True)

docs = [MyDoc(text=f'text {i}', embedding=np.random.rand(10)) for i in range(10)]
query = np.random.rand(10)
db = MilvusDocumentIndex[MyDoc]()
db.index(docs)
results = db.find(query, limit=10)

In this example, we're creating a document class with both textual and numeric data. Then, we initialize a Milvus-backed document index and use it to index our documents. Finally, we perform a search query.

Supported Functionalities

• Find: Vector search for efficient retrieval of similar documents.
• Filter: Use Redis syntax to filter based on textual and numeric data.
• Get/Del: Fetch or delete specific documents from the index.
• Hybrid Search: Combine find and filter functionalities for more refined search.
• Subindex: Search through nested data.

Support filtering in HnswDocumentIndex (#1718)

With our latest update, you can easily utilize filtering in HnswDocumentIndex either as an independent function or in conjunction with the query builder to combine it with vector search.

The code below shows how the new feature works:

import numpy as np

from docarray import BaseDoc, DocList
from docarray.index import HnswDocumentIndex
from docarray.typing import NdArray


class SimpleSchema(BaseDoc):
    year: int
    price: int
    embedding: NdArray[128]


# Create dummy documents.
docs = DocList[SimpleSchema](
    SimpleSchema(year=2000 - i, price=i, embedding=np.random.rand(128))
    for i in range(10)
)

doc_index = HnswDocumentIndex[SimpleSchema](work_dir="./tmp_5")
doc_index.index(docs)

# Independent filtering operation (year == 1995)
filter_query = {"year": {"$eq": 1995}}
results = doc_index.filter(filter_query)

# Filtering combined with vector search
hybrid_query = (
    doc_index.build_query()  # get empty query object
    .filter(filter_query={"year": {"$gt": 1994}})  # pre-filtering (year > 1994)
    .find(
        query=np.random.rand(128), search_field="embedding"
    )  # add vector similarity search
    .filter(filter_query={"price": {"$lte": 3}})  # post-filtering (price <= 3)
    .build()
)
results = doc_index.execute_query(hybrid_query)

First, we create and index some dummy documents. Then, we use the filter function in two ways. One is by itself to find documents from a specific year. The other is mixed with a vector search, where we first filter by year, perform a vector search, and then filter by price.

Pre-filtering in InMemoryExactNNIndex (#1713)

You can now add a pre-filter to your queries in InMemoryExactNNIndex. This lets you create flexible queries where you can set up as many pre- and post-filters as you want. Here's a simple example:

query = (
   doc_index.build_query()
   .filter(filter_query={'price': {'$lte': 3}})  # Pre-filter: price <= 3
   .find(query=np.ones(10), search_field='tensor')  # Vector search
   .filter(filter_query={'text': {'$eq': 'hello 1'}})  # Post-filter: text == 'hello 1'
   .build()
)

In this example, we first set a pre-filter to only include items priced 3 or less. We then do a vector search. Lastly, we add a post-filter to find items with the text 'hello 1'. This way, you can easily filter before and after your search!

Support document updates in InMemoryExactNNIndex (#1724)

You can now easily update your documents in InMemoryExactNNIndex. Previously, when you tried to update the same set of documents, it would just add duplicate copies instead of making changes to the existing ones. But not anymore! From now on, If you want to update documents you just have to re-index them.

Choose tensor format with DocVec deserialization (#1679)

Now you can specify the format of your tensor during DocVec deserialization. You can do this with any method you're using to convert data - like protobuf, json, pandas, bytes, binary, or base64. This means you'll always get your tensors in the format you want, whether it's a Torch tensor, TensorFlow tensor, NDarray, and so on.

Add description and example to id field of BaseDoc (#1737)

We added a description and example to the id field of BaseDoc, so that you get a richer OpenAPI specification when building FastAPI based applications with it.

🚀 Performance

Improve HnswDocumentIndex performance (#1727, #1729)

We've implemented two key optimizations to enhance the performance of HnswDocumentIndex. Firstly, we've avoided serialization of embeddings to SQLite, which is a costly operation and unnecessary as the embeddings can be reconstructed from hnswlib index itself. Additionally, we've minimized the frequency of computing num_docs(), which previously involved time-consuming full table scan to determine the number of documents in SQLite. As a result, we've seen an approximate speed increase of 10%, enhancing both the indexing and searching processes.

🐞 Bug Fixes

Fix TorchTensor type comparison (#1739)

We have addressed an exception raised when trying to compare TorchTensor with the type keyword in the docarray.typing module. Previously, this would lead to a TypeError, but the error has now been resolved, ensuring proper type comparison.

Add more info from dynamic class (#1733)

When using the method create_base_doc_from_schema to dynamically create a BaseDoc class, some information was lost, so we made sure that the new class keeps FieldInfo information from the original class such as description and examples.

Fix call to unsafe issubclass (#1731)

We fixed a bug calling issubclass by changing the call for a safer implementation against some types.

Align collection and index name in QdrantDocumentIndex (#1723)

We've corrected an issue where the collection name was not being updated to match a newly-initialized subindex name in QdrantDocumentIndex. This ensures consistent naming between collections and their respective subindexes.

Fix deepcopy TorchTensor (#1720)

We fixed a bug that will allow deepcopying documents with TorchTensors.

📗 Documentation Improvements

This release contains 2 new features, 5 bug fixes, 1 performance improvement and 1 documentation improvement.

🆕 Features

JAX Integration (#1646)

You can now use JAX with Docarray. We have introduced JaxArray as a new type option for your documents. JaxArray ensures that JAX can now natively process any array-like data in your DocArray documents. Here's how you use of it:

from docarray import BaseDoc
from docarray.typing import JaxArray
import jax.numpy as jnp


class MyDoc(BaseDoc):
    arr: JaxArray
    image_arr: JaxArray[3, 224, 224] # For images of shape (3, 224, 224)
    square_crop: JaxArray[3, 'x', 'x'] # For any square image, regardless of dimensions
    random_image: JaxArray[3, ...]  # For any image with 3 color channels, and arbitrary other dimensions

As you can see, the JaxArray typing is extremely flexible and can support a wide range of tensor shapes.

Creating a Document with Tensors

Creating a document with tensors is straightforward. Here is an example:

doc = MyDoc(
    arr=jnp.zeros((128,)),
    image_arr=jnp.zeros((3, 224, 224)),
    square_crop=jnp.zeros((3, 64, 64)),
    random_image=jnp.zeros((3, 128, 256)),
)

Redis Integration (#1550)

Leverage the power of Redis in your Docarray project with this latest integration. Here's a simple usage example:

import numpy as np
from docarray import BaseDoc
from docarray.index import RedisDocumentIndex
from docarray.typing import NdArray


class MyDoc(BaseDoc):
    text: str
    embedding: NdArray[10]

docs = [MyDoc(text=f'text {i}', embedding=np.random.rand(10)) for i in range(10)]
query = np.random.rand(10)
db = RedisDocumentIndex[MyDoc](host='localhost')
db.index(docs)
results = db.find(query, search_field='embedding', limit=10)

In this example, we're creating a document class with both textual and numeric data. Then, we initialize a Redis-backed document index and use it to index our documents. Finally, we perform a search query.

Supported Functionalities

Find: Vector search for efficient retrieval of similar documents.
Filter: Use Redis syntax to filter based on textual and numeric data.
Text Search: Leverage text search methods, such as BM25, to find relevant documents.
Get/Del: Fetch or delete specific documents from the index.
Hybrid Search: Combine find and filter functionalities for more refined search. Currently, only these two can be combined.
Subindex: Search through nested data.

🚀 Performance

Speedup HnswDocumentIndex by caching num docs (#1706)

We've optimized the num_docs() operation by caching the document count, addressing previous slowdowns during searches. This change results in a minor increase in indexing time, but significantly accelerates search times.

from docarray import BaseDoc, DocList
from docarray.index import HnswDocumentIndex
from docarray.typing import NdArray
import numpy as np
import time

class MyDoc(BaseDoc):
    text: str
    embedding: NdArray[128]


docs = [MyDoc(text='hey', embedding=np.random.rand(128)) for _ in range(20000)]
index = HnswDocumentIndex[MyDoc](work_dir='tst', index_name='index')

index_start = time.time()
index.index(docs=DocList[MyDoc](docs))
index_time = time.time() - index_start

query = docs[0]

find_start = time.time()
matches, _ = index.find(query, search_field='embedding', limit=10)
find_time = time.time() - find_start

In the above experiment, we observed a 13x improvement in the speed of the search function, reducing its execution time from 0.0238 to 0.0018 seconds.

⚙ Refactoring

Put Contains method in the base class (#1701)

We've moved the contains method into the base class. With this refactoring, the responsibility for checking if a document exists is now delegated to individual backend implementations using the new _doc_exists method.

More robust method to detect duplicate index (#1651)

We have implemented a more robust method of detecting existing indices for WeaviateDocumentIndex

🐞 Bug Fixes

WeaviateDocumentIndex handles lowercase index names (#1711)

We've addressed an issue in the WeaviateDocumentIndex where passing a lowercase index name led to mismatches and subsequent errors. This was due to the system automatically capitalizing the index name when creating an index.

QdrantDocumentIndex unable to see index_name (#1705)

We've resolved an issue where the QdrantDocumentIndex was not properly recognizing the index_name parameter. Previously, the specified index_name was ignored and the system defaulted to the schema name.

Fix search in InMemoryExactNNIndex with AnyEmbedding (#1696)

From now on, you can perform search operations in InMemoryExactNNIndex using AnyEmbedding

Use safe_issubclass everywhere (#1691)

We now use safe_issubclass instead of issubclass because it supports non-class inputs, helping us to avoid unexpected errors

Avoid converting DocLists in the base index (#1685)

We added an additional check to avoid passing DocLists to a function that converts a list of dictionaries to a DocList.

📗 Documentation Improvements

• Add docs for dict() method (#1643)

Release Note (0.35.0)

This release contains 3 new features, 2 bug fixes and 1 documentation improvement.

🆕 Features

More serialization options for DocVec (#1562)

DocVec now has the same serialization interface as DocList. This means that that following methods are available for it:

• to_protobuf()/from_protobuf()
• to_base64()/from_base64()
• save_binary()/load_binary()
• to_bytes()/from_bytes()
• to_dataframe()/from_dataframe()

For example, you can now perform Base64 (de)serialization like this:

from docarray import BaseDoc, DocVec

class SimpleDoc(BaseDoc):
    text: str

dv = DocVec[SimpleDoc]([SimpleDoc(text=f'doc {i}') for i in range(2)])
base64_repr_dv = dv.to_base64(compress=None, protocol='pickle')

dl_from_base64 = DocVec[SimpleDoc].from_base64(
    base64_repr_dv, compress=None, protocol='pickle'
)

For further guidance, check out the documentation section on serialization.

Validate file formats in URL (#1606) (#1669)

Validate the file formats given in URL types such as AudioURL, TextURL, ImageURL to check they correspond to the expected mime type.

Add methods to create BaseDoc from schema (#1667)

Sometimes it can be useful to dynamically create a BaseDoc from a given schema of an original BaseDoc. Using the methods create_pure_python_type_model and create_base_doc_from_schema you can make sure to reconstruct the BaseDoc.

from docarray.utils.create_dynamic_doc_class import (
    create_base_doc_from_schema,
    create_pure_python_type_model,
)

from typing import Optional
from docarray import BaseDoc, DocList
from docarray.typing import AnyTensor
from docarray.documents import TextDoc

class MyDoc(BaseDoc):
    tensor: Optional[AnyTensor]
    texts: DocList[TextDoc]

🐞 Bug Fixes

Cap Pydantic version (#1682)

Due to the breaking change in Pydantic v2, we have capped the version to avoid problems when installing docarray.

Better error message when DocVec is unusable (#1675)

After calling doc_list = doc_vec.to_doc_list(), doc_vec ends up in an unusable state since its data has been transferred to doc_list. This fix gives users a more informative error message when they try to interact with doc_vec after it has been made unusable.

📗 Documentation Improvements

• Fix a reference in README (#1674)
