Processes scan segments in parallel and a given process can scan `druid.processing.numThreads` concurrently. To process more data in parallel and increase performance, more cores can be added to a cluster. Druid segments should be sized such that any computation over any given segment should complete in at most 500ms. The metric you need to check for this is [`query/segment/time`](../operations/metrics.md#historical). Review Comment: ```suggestion Druid's fundamental unit of computation is a [segment](../design/segments.md). Processes scan segments in parallel and a given process can scan `druid.processing.numThreads` concurrently. You can add more cores to a cluster to process more data in parallel and increase performance. Size your Druid segments such that any computation over any given segment should complete in at most 500ms. Use the the [`query/segment/time`](../operations/metrics.md#historical) metric to monitor computation times. ``` -- This is an automated message from the Apache Git Service.
