A Rust Client for InfluxDB 3

InfluxDB has introduced influxdb3-client, an asynchronous Rust client for InfluxDB 3 Core and Enterprise aimed at embedded systems, edge gateways, and high-throughput telemetry pipelines. Built for Rust 1.89 or later, it provides an idiomatic API for writing line protocol, points, and optionally Polars DataFrames; querying with SQL or InfluxQL; and receiving results as rows or native Apache Arrow RecordBatches. The client supports shared deployment configurations through builders, environment variables, and connection strings, defaults to the broadly compatible V2 write endpoint, and can enable V3-specific options such as no-sync acknowledgments and partial-write reporting. Its ingest features include bounded batching, configurable concurrent requests, tag ordering controls, retries with exponential backoff for transient failures, and support for streaming large query results. Optional Polars integration enables Arrow-native DataFrame workflows and migrations from Parquet or CSV, while documentation, examples, source code, and package distribution are available through docs.rs, GitHub, and crates.io.
