Attributes

explicit_schema	Optional explicit schema (no type inference, ignores other fields)
newlines_in_values	Whether newline characters are allowed in JSON values.
unexpected_field_behavior	How JSON fields outside of explicit_schema (if given) are treated.

Parameters:

otherpyarrow.json.ParseOptions

Returns:

bool

explicit_schema#

Optional explicit schema (no type inference, ignores other fields)

newlines_in_values#

Whether newline characters are allowed in JSON values. Setting this to True reduces the performance of multi-threaded JSON reading.

unexpected_field_behavior#

How JSON fields outside of explicit_schema (if given) are treated.

• ignore: unexpected JSON fields are ignored

• error: error out on unexpected JSON fields

• infer: unexpected JSON fields are type-inferred and included in the output
