    QuestDB is a high-performance open-source database for time series. The project is built from scratch in Java and C++ with no dependencies and zero garbage collection. It is optimized for high-throughput ingestion over InfluxDB line protocol and fast SQL queries. QuestDB is also one of the most popular time series databases according to the independent reviewer DBEngines.

    Vlad is the creator of the open source QuestDB project. He used the sun.misc.Unsafe class to implement fast memory access in Java and provide native level performance for the DB without GC. You can allocate a massive array in native RAM and traverse it without data copying. This lets Java and C code interact much faster than the typical slow JNI bridge.

    As usual, there are edge cases and hidden reefs, so the implementation is not as simple as it may sound. Say, what if your query has a filter and a LIMIT -10 clause, just like in our recent benchmark? Then the database should execute the query in parallel, fetch the last 10 records and cancel the remaining page frame filtering tasks, so that there is no useless filtering done by other worker threads. A similar cancellation should take place in the face of a closed PGWire or HTTP connection or a query execution timeout. So, as you already saw in the above comparison, we made sure to handle all of these edge cases. If you're interested in the implementation details, go check this lengthy pull request.
