[GitHub] [incubator-pinot] ly923976094 opened a new issue #3978: The
segments are stored in memory
ly923976094 opened a new issue #3978: The segments are stored in memory
URL: https://github.com/apache/incubator-pinot/issues/3978
Once segments are assigned, Pinot servers get notified via Helix to “host” the segment. The servers download the segments (as a cached local copy to serve queries) and load them into local memory. All segment data is maintained in memory as long as the server hosts that segment.
I want to know which segments are permanently loaded into the memory, and whether the memory is expensive and the data volume is large
