PlyQL

PlyQL (v0.11.2) is a SQL-like query interface for Plywood, primarily used for querying Druid databases. It provides a command-line tool that translates SQL-style queries into Plywood expressions and executes them against Druid. The package supports various output formats (JSON, CSV, TSV, flat), query timeouts, retries, concurrency limits, Druid-specific options like rollup mode, introspection strategies, and column type forcing. It requires Node >= 4.x.x and has no major updates recently, indicating maintenance mode. Alternatives include direct Druid SQL or Plywood native queries, but PlyQL offers a familiar SQL syntax for users accustomed to relational databases. The package is authored by Imply and has a low release cadence.
