In previous Radars we've discussed PostgreSQL for NoSQL. PostgreSQL's maturity and extensibility have led to a steady stream of innovative persistence stores built on the Postgres engine. One that caught our attention is TimescaleDB, a database that allows fast writes and optimized queries over time-series data. Albeit not (yet) as full-featured as InfluxDB, TimescaleDB offers an alternative data model and querying capability. You should evaluate TimescaleDB if you have modest scalability needs, prefer to use SQL and appreciate the stability and familiar administrative interface that PostgreSQL offers.
