QuestDB is happiest when data arrives in order. Live data, on the other hand, often arrives out of order, especially when it comes from several feeds or from parallel senders. When that happens, QuestDB has to write the affected partitions again with the late rows merged in. Meanwhile a lot of everyday analysis still happens just outside the database: a chart library thinning millions of points, a notebook computing a p99 that SQL could only approximate, a separate monitoring stack collecting QuestDB’s own metrics. QuestDB 10.1 writes late data with less I/O and makes it readable sooner, and brings those other jobs into SQL.
