0.20.0

Features

1. #208: Add influx3 query CLI support for executing SQL/InfluxQL queries with JSON/JSONL/CSV/pretty output, including module execution via python -m influxdb_client_3.
2. #213: Add partial write support and default writes to the V2 API endpoint.
   See Partial writes for more.
   no_sync requires use_v2_api=False; accept_partial applies only to V3 API endpoint writes.

Others

1. #215:
   • Remove cookie/session-based signin/signout support from the writing client.
   • Remove basic authentication with a username and password.

0.19.0

Features

1. #198: Support custom tag order via tag_order write option.
   See Sort tags by priority for more.
2. #202: Add escape for field keys when serializing to line protocol in PolarsDataframeSerializer.

0.18.0

Features

1. #196: Support passing middleware functions to the Flight client.

Bug Fixes

1. #194: Fix InfluxDBClient3.write_file() and InfluxDBClient3.write_dataframe() fail with batching mode.
2. #197: InfluxDB 3 Core/Enterprise write errors details handling.

0.17.0

Features

1. #177: Add dedicated DataFrame methods for improved usability and type safety:
   • write_dataframe(): New method for writing pandas and polars DataFrames with explicit parameters (measurement, timestamp_column, tags, timestamp_timezone).
   • query_dataframe(): New method for querying data directly to a pandas or polars DataFrame via the frame_type parameter.
   • Updated README with clear examples for DataFrame operations.
2. #179: Add option to disable gRPC response
   compression for Flight queries:
   • disable_grpc_compression parameter in InfluxDBClient3 constructor
   • INFLUX_DISABLE_GRPC_COMPRESSION environment variable support in from_env()
3. #180: Add flush() method to InfluxDBClient3:
   • Allows flushing the write buffer without closing the client when using batching mode.
   • Enables applications to ensure data is written before querying, while keeping the client open for further operations.

Bug Fixes

1. #177: Fix TypeError when writing DataFrames. Serializer-specific kwargs (e.g., data_frame_measurement_name) are now filtered before being passed to the HTTP layer.
