InfluxDB Cloud Serverless internals
Arrow Flight SQL
The InfluxDB SQL implementation uses Arrow Flight SQL to query InfluxDB and return results.
InfluxDB Cloud Serverless data durability
InfluxDB Cloud Serverless 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 Serverless
InfluxDB Cloud Serverless enforces bucket retention periods at query time and, to optimize storage, routinely deletes Parquet files containing only expired data.
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.
