InfluxDB internals

InfluxDB storage engine

An overview of the InfluxDB storage engine architecture.

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 runtime

Learn how to collect Go runtime profiling and tracing information to help with InfluxDB performance analysis and debugging.

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.

InfluxDB system buckets

InfluxDB system buckets contain time series data used by and generated from the InfluxDB monitoring and alerting system and the task engine.
