This change is to emit following metrics as part of GroupByStatsMonitor monitor,
mergeBuffer/used -> Number of merge buffers used.
mergeBuffer/acquisitionTimeNs -> Total time required to acquire merge buffer.
mergeBuffer/acquisition -> Number of queries that acquired a batch of merge buffers.
groupBy/spilledQueries -> Number of queries that spilled onto the disk.
groupBy/spilledBytes-> Spilled bytes on the disk.
groupBy/mergeDictionarySize -> Size of the merging dictionary.
All JDK 8 based CI checks have been removed.
Images used in Dockerfile(s) have been updated to Java 17 based images.
Documentation has been updated accordingly.
* SQL syntax error should target USER persona
* * revert change to queryHandler and related tests, based on review comments
* * add test
* * add `ingest/notices/queueSize` and `ingest/pause/time` to statsd emitter
* * add taskStatus dimension to `service/heartbeat` metric
* Revert "* add taskStatus dimension to `service/heartbeat` metric"
This reverts commit cfb02a2813b24243ea0703def7a0dddd948bee00.
changes:
* fix issue when merging projections from multiple-incremental persists which was hoping that some 'dim conversion' buffers were not closed, but they already were (by the merging iterator). fix involves selectively persisting these conversion buffers to temp files in the segment write out directory and mapping them and tying them to the segment level closer so that they are available after the lifetime of the parent merger
* modify auto column serializers to use segment write out directory for temp files instead of java.io.tmpdir
* fix queryable index projection to not put the time-like column as a dimension, instead only adding it as __time
* use smoosh for temp files so can safely write any Serializer to a temp smoosh
* SQL syntax error should target USER persona
* * revert change to queryHandler and related tests, based on review comments
* * add test
* Add 'ingest/notices/time' metric to statsd emitter
This metric gives the milliseconds taken to process a notice by the supervisor.
