Compact a series file offline

This page documents an earlier version of InfluxDB OSS. InfluxDB OSS v2 is the latest stable version. See the InfluxDB v2 documentation.

Use the Series File Compaction tool to compact your series file and reduce its size on disk. This is useful for series files that grow quickly, for example, when series are frequently created and deleted.

To compact a series file:

  1. Stop the influxd process.

  2. Run the following command, including your data directory and WAL directory:

    # Syntax
    influx_inspect buildtsi -compact-series-file -datadir <data_dir> -waldir <wal_dir>
    
    # Example
    influx_inspect buildtsi -compact-series-file -datadir /data -waldir /wal
    
    • Copy
    • Fill window
  3. Restart the influxd process.

  4. (InfluxDB Enterprise only) On each data node:

    1. Complete steps 1-3.
    2. Wait for the hinted handoff queue (HHQ) to write all missed data to the node.
    3. Continue to the next data node.
