InfluxDB internals
Limited availability
InfluxDB Clustered is currently only available to a limited group of InfluxData customers. If interested in being part of the limited access group, please contact the InfluxData Sales team.
Arrow Flight SQL
The InfluxDB SQL implementation uses Arrow Flight SQL to query InfluxDB and return results.
Data retention in InfluxDB Clustered
InfluxDB Clustered enforces database retention periods at query time and, to optimize storage, routinely deletes Parquet files containing only expired data.
InfluxDB system tables
InfluxDB system measurements contain time series data used by and generated from the InfluxDB internal monitoring system.
InfluxDB v3 storage engine architecture
The InfluxDB v3 storage engine is a real-time, columnar database optimized for time series data that supports infinite tag cardinality, real-time queries, and is optimized to reduce storage cost.
Query plans
A query plan is a sequence of steps that the InfluxDB Querier devises and executes to calculate the result of a query in the least amount of time. InfluxDB query plans include DataFusion and InfluxDB logical plan and execution plan nodes for scanning, deduplicating, filtering, merging, and sorting data.
