influxdb3-rust release notes

v0.2.0

Features

1. #12: Expand client configuration support for environment variables and connection strings. Add auth scheme and write option support. Preserve explicit ports and strip userinfo from normalized hosts. Remove the legacy bucket and INFLUX_BUCKET aliases in favor of database and INFLUX_DATABASE.
2. #19: Default writes to the V2 API endpoint. Add builder methods for write defaults. no_sync requires use_v2_api=false to write to the V3 API endpoint. accept_partial applies only when writes are sent to the V3 API endpoint and is ignored otherwise.

Bug Fixes

1. #13: Improve Arrow query result type support. Unsupported Arrow types now produce Error::UnsupportedArrowType instead of Null.

Dependencies

1. #18: Upgrade Arrow dependencies to version 58 and require Rust 1.89 or later.

v0.1.0

Initial release.

Features

• Async client for InfluxDB 3 Core and Enterprise over HTTP (writes) and Arrow Flight (queries).
• Write API: a builder accepting line-protocol strings, Vec<Point>, and (with the polars feature) a DataFrame. Options for timestamp precision, batching, in-flight concurrency, default tags, gzip, and WAL no-sync.
• Query API: SQL and InfluxQL, parameterised queries, row iteration, and streaming of results too large to hold in memory.
• Automatic retries with exponential backoff and full jitter for transient failures (transport errors, 429, 5xx), honouring Retry-After. Configurable per client or per request.
• Partial-write error reporting with per-line detail.
• Optional polars feature: DataFrame writes and query-to-DataFrame conversion.

Notes

• Retries are enabled by default (max_retries = 3). Use .no_retry() or a custom RetryConfig to change this.
