Features

1. #159: Support fast writes without waiting for WAL
   persistence:

     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").

   • 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.

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.

2.0.0

2.0.0 [2024-12-13]

Breaking Changes

⚠️ This is a breaking change release.

Previously, the Query API did not respect the metadata type for columns returned from InfluxDB v3. This release fixes this issue. As a result, the type of some columns may differ from previous versions. For example, the timestamp column will now be time.Time instead of arrow.Timestamp.

Update steps:

1. Update library: go get github.com/InfluxCommunity/influxdb3-go/v2/influxdb3
2. Update import path in Go files to github.com/InfluxCommunity/influxdb3-go/v2/influxdb3.

Features

1. #114: Query API respects metadata types for columns returned from InfluxDB v3.
   Tags are mapped as a "string", timestamp as "time.Time", and fields as their respective types:
   • iox::column_type::field::integer: => int64
   • iox::column_type::field::uinteger: => uint64
   • iox::column_type::field::float: => float64
   • iox::column_type::field::string: => string
   • iox::column_type::field::boolean: => bool

v1.0.0

⚠️ The v1.0.0 release had a malformed module path regarding the Go Module Requirements. For a Go Module project, you need to use version 2 of the client.
