Features

1. 192: Add clearer timeout parameters.
   • The ClientConfig property Timeout is now deprecated.
   • In ClientConfig a new property WriteTimeout supersedes it.
   • In ClientConfig the new property QueryTimeout sets a default context deadline to be used with all queries.
   • New environment variables INFLUXDB_WRITE_TIMEOUT and INFLUXDB_QUERY_TIMEOUT are added.

Bug Fixes

1. #193: Use influxdb3_test package in the documentation examples to enforce public API usage.

Features

1. #189: Add transparent gRPC compression support

CI

1. #180:
   • Add tests for arm64 CircleCI.
   • Add tests for go v1.24 and v1.25.

Features

1. #169: Support user-defined type converter function for writes points.
2. #171: Add function to get InfluxDB version.
3. #176: Add comment warning null when calling getMeasurement function.
4. #174: Run integration tests against a locally started InfluxDB 3 Core server.

Features

1. #159: Support fast writes without waiting for WAL
   persistence:
   • New write option (WriteOptions.NoSync) added: true value means faster write but without the confirmation that
     the data was persisted. Default value: false.
   • Supported by self-managed InfluxDB 3 Core and Enterprise servers only!
   • Also configurable via connection string query parameter (writeNoSync).
   • Also configurable via environment variable (INFLUX_WRITE_NO_SYNC).
   • Long precision string values added from v3 HTTP API: "nanosecond", "microsecond", "millisecond", "second" (
     in addition to the existing "ns", "us", "ms", "s").

1. #164: Updates
   • Go version to 1.23.9
   • golang.org/x/net to v0.38.0
2. #166: Upgrades dependency apache/arrow/go to apache/arrow-go v18.

Bug Fixes

1. #158: Refactor Batcher and LPBatcher:
   • Fields and methods using capacity renamed to initialCapacity.
   • Log messages when buffer data is not being emitted are simplified.
   • SetCapacity methods on both structures are now deprecated.
   • WithCapacity and WithBufferCapacity options are now deprecated.

Features

1. #155: Batcher warnings when buffer data is not being automatically emitted changed to level Debug in slog.

Features

1. #146: Add error field to QueryIterator to hold first possible error encountered when retrieving records from the flight Reader.
2. #147: Ability to pass grpc.CallOption functions to the underlying flight Client.
3. #149: Add default configuration for the built-in HTTP
   client and expose new configurable parameters:
   • Timeout - The overall time limit for requests made by the Client. A negative value means no timeout. Default
     value: 10 seconds.
   • IdleConnectionTimeout - Maximum time an idle connection will remain idle before closing itself. A negative value
     means no timeout. Default value: 90 seconds.
   • MaxIdleConnections - Maximum number of idle connections. It sets both transport.MaxIdleConn and
     transport.MaxIdleConnsPerHost to the same value. A negative value means no limit. Default value: 100.
4. #154: Export functions NewQueryIterator and
   NewPointValueIterator to simplify testing.

Features

1. #141: Add proxy and custom SSL root certificate support.
