GreptimeDB has implemented PromQL natively in its query planner, allowing direct execution and analysis with tools like EXPLAIN ANALYZE without translating it to SQL.
GreptimeDB v1.3.0-alpha.1 introduces PromQL native histograms and vector operators for enhanced observability, with added support for OTLP traces and RISC-V 64 builds.
GreptimeDB v1.1.0 is released, offering up to 97% faster PromQL queries, 20-40% lower overall query times, and up to 4.5x improvement on TSBS scan-heavy queries, along with online repartitioning for existing tables.
Greptime released version 0.9.0 of promql-parser, a Rust-based PromQL parser featuring declarative function refactoring and support for limit functions.
