InfluxDB storage engine

An overview of the InfluxDB storage engine architecture.

Manage the InfluxDB time series index (TSI)

The InfluxDB time series index (TSI) indexes or caches measurement and tag data to ensure queries are performant. Use the influxd inspect command to manage the TSI index.

InfluxDB file system layout

The InfluxDB file system layout depends on the operating system, package manager, or containerization platform used to install InfluxDB.

Data retention in InfluxDB

The InfluxDB retention service checks for and removes data with timestamps beyond the defined retention period of the bucket the data is stored in.

InfluxDB shards and shard groups

Learn the relationships between buckets, shards, and shard groups. InfluxDB organizes time series data into shards when storing data to disk. Shards are grouped into shard groups.

Rebuild the TSI index

Flush and rebuild the TSI index to purge corrupt index files or remove indexed data that is out of date.

Inspect TSI indexes

Use the influxd inspect command to inspect the InfluxDB TSI index.
