Elasticsearch

Elasticsearch is a distributed Lucene-based search engine — the de-facto choice for full-text search, log aggregation, and faceted filtering at scale. TantraDev uses Elasticsearch (or OpenSearch where licensing matters) when full-text relevance, aggregation, and near-real-time indexing all have to coexist. For pure log search the calculus is different — Loki or ClickHouse often wins on cost.

TECHNOLOGY

PostgreSQL

PostgreSQL is an open-source relational database with strong ACID guarantees, MVCC concurrency, and rich extension surface (PostGIS, pg_partman, logical replication). It is the default datastore on every TantraDev engagement where the workload is transactional, the data has relationships, and the team needs the option to scale via partitioning and read replicas before reaching for a specialised store.
