SereneDB

SereneDB is the result of 12 years of development - an open-source database that does ultra-fast full-text and fast analytics in one engine. Postgres- and Elastic-compatible: keep your SQL, your drivers, and your Elastic clients; drop the second system and the ETL between them. In our public benchmark, it outperforms Elasticsearch, ClickHouse, and Postgres search extensions, and indexes 1B logs in under 8 minutes at ~10x less disk. Apache 2.0, methodology, and raw results are public.
