QuestDB Time Series

QuestDB is a high-performance, open-source time series database designed for ingesting and querying massive volumes of timestamped data. Built for columnar storage and vectorized execution, QuestDB achieves ingestion rates exceeding 1 million rows/second and queries on billions of rows completing in milliseconds. Unlike NoSQL alternatives (InfluxDB, MongoDB), QuestDB is SQL-native, enabling complex analytical queries on time series data without learning custom query languages. Financial institutions, energy companies, IoT platforms, and observability teams handle trillions of time series data points daily. QuestDB's performance advantages and SQL simplicity make it increasingly attractive for teams that previously used Elasticsearch, InfluxDB, or PostgreSQL. Expertise in QuestDB is still specialized and relatively rare, commanding 20–35% premiums for specialists and opening doors to data engineering and analytics roles at scale-heavy organizations.
