InfluxDB v2.0.5 Release Notes

Release Date: 2021-04-27 // almost 3 years ago

  • 🏁 Windows Support

    🚀 This release includes our initial Windows preview build.

    💥 Breaking Changes

    🚚 /debug/vars removed

    🚀 Prior to this release, the influxd server would always expose profiling information over /debug/vars. 🔒 This endpoint was unauthenticated, and not used by InfluxDB systems to report diagnostics. For security and clarity, 🚚 the endpoint has been removed. Use the /metrics endpoint to collect system statistics.

    🚚 influx transpile removed

    The transpile command has been retired. Users can send InfluxQL directly to the server via the /api/v2/query or /query HTTP endpoints.

    0️⃣ Default query concurrency changed

    0️⃣ The default setting for the max number of concurrent Flux queries has been changed from 10 to unlimited. Set the query-concurrency config parameter to > 0 when running influxd to re-limit the maximum running query count, and the query-queue-size config parameter to > 0 to set the max number of queries that can be queued before the server starts rejecting requests.

    Prefix for query-controller metrics changed

    The prefix used for Prometheus metrics from the query controller has changed from query_control_ to qc_.
