InfluxDB has cycled through three query languages across three major versions — InfluxQL, Flux, and now SQL — forcing industrial teams into repeated migrations. Each migration carries real costs: Grafana dashboards must be manually rewritten, application code using Flux client libraries must be replaced, and team knowledge built around Flux becomes obsolete. Standard SQL, stable since 1986, avoids this churn. SQL supports all the time-series patterns industrial teams need (DATE_BIN, window functions, JOINs) and works natively with every BI tool, data pipeline framework, and PostgreSQL-compatible driver. Teams currently on InfluxDB 2.x with Flux queries face a migration regardless — the argument is that migrating to a SQL-native database like CrateDB lands them on a stable, broadly compatible foundation rather than another purpose-built time-series store that may change its query model again.
