InfluxDB internals

Arrow Flight SQL

The InfluxDB SQL implementation uses Arrow Flight SQL to query InfluxDB and return results.

InfluxDB Cloud Dedicated security

InfluxDB Cloud Dedicated is built on industry-standard security practices and principles.

InfluxDB Cloud Dedicated data durability

InfluxDB Cloud Dedicated replicates all time series data in the storage tier across multiple availability zones within a cloud region and automatically creates backups that can be used to restore data in the event of a node failure or data corruption.

Data retention in InfluxDB Cloud Dedicated

InfluxDB Cloud Dedicated 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.
