The CVE details are here - https://nvd.nist.gov/vuln/detail/CVE-2021-26291. I am marking it suppressed since we are only using kafka-clients jar in druid. We use maven-artifact jar ourselves but it is only used for comparing versions
* Improve concurrency between DruidSchema and BrokerServerView
* unused imports and workaround for error prone faiure
* count only known segments
* add comments
* add typeIs
* fix unused field in count metric
* better types
* typos
* work with readonly types
* factor out apply cancel buttons
* form editor
* selection type
* unsaved changes
* form editor spec
* tidy up sampler
* more menu controls
* update e2e test
* Update default maxSegmentsInNodeLoadingQueue
Update the default maxSegmentsInNodeLoadingQueue from 0 (unbounded) to 100.
An unbounded maxSegmentsInNodeLoadingQueue can cause cluster instability.
Since this is the default druid operators need to run into this instability
and then look through the docs to see that the recommended value for a large
cluster is 1000. This change makes it so the default will prevent clusters
from falling over as they grow over time.
* update tests
* codestyle
* Better logging for lookups
The default pollPeriod of 0 means that lookups are loaded once only at startup
Add a warning message to warn operators about this. I suspect that most
operators using jdbc or uri would expect eventual consistency with the source
of the lookups if using jdbc or uri. So make this a warning to make it easier
to debug if an operator notices a data inconsistency issue.
* oops
* Add a note
* Update docs/configuration/index.md

This change allows the selection of a specific broker service (or broker tier) by the Router.
The newly added ManualTieredBrokerSelectorStrategy works as follows:
Check for the parameter brokerService in the query context. If this is a valid broker service, use it.
Check if the field defaultManualBrokerService has been set in the strategy. If this is a valid broker service, use it.
Move on to the next strategy
This PR fixes an issue with the integration test copy_resources.sh script.
The "install druid jars" portion was removing the $SHARED_DIR/docker directory, which wipes out the $SHARED_DIR/docker/extensions and $SHARED_DIR/docker/credentials directories created just before, which leads to issues later in the script when copying resources to the $SHARED_DIR/docker/credentials/ dir.
* HLL lgK and a tip
Knowledge transfer from https://the-asf.slack.com/archives/CJ8D1JTB8/p1600699967024200. Attempted to make a connection between the SQL HLL function and the HLL underneath without getting too complicated. Also added a note about using K over 16 being pretty much pointless.
* Corrected spelling
* Create datasketches-hll.md
Put roll-up back to rollup
* Update docs/development/extensions-core/datasketches-hll.md

This PR fixes the incorrect results for query :
SELECT dim1, l1.k FROM foo LEFT JOIN (select k || '' as k from lookup.lookyloo group by 1) l1 ON foo.dim1 = l1.k WHERE l1.k IS NOT NULL (in CalciteQueryTests)
In the current code, the WHERE clause gets removed from the top of the left join and is pushed to the table foo
leading to incorrect results.
The fix for such a situation is done by :
Converting such left joins into inner joins (since logically the mentioned left join query is equivalent to an inner join) using Calcite while maintaining that the druid execution layer can execute such inner joins.
Preferring converted inner joins over original left joins in our cost model
* Add a new metric query/segments/count that is not emitted by default
* docs
* test the default implementation of the metric
* fix spelling error in docs
* document the fact that query retries will result in additional metric emissions
* update using recommended text from @jihoonson
This PR refactors the code related to segment loading specifically SegmentLoader and SegmentLoaderLocalCacheManager. SegmentLoader is marked UnstableAPI which means, it can be extended outside core druid in custom extensions. Here is a summary of changes
SegmentLoader returns an instance of ReferenceCountingSegment instead of Segment. Earlier, SegmentManager was wrapping Segment objects inside ReferenceCountingSegment. That is now moved to SegmentLoader. With this, a custom implementation can track the references of segments. It also allows them to create custom ReferenceCountingSegment implementations. For this reason, the constructor visibility in ReferenceCountingSegment is changed from private to protected.
SegmentCacheManager has two additional methods called - reserve(DataSegment) and release(DataSegment). These methods let the caller reserve or release space without calling SegmentLoader#getSegment. We already had similar methods in StorageLocation and now they are available in SegmentCacheManager too which wraps multiple locations.
Refactoring to simplify the code in SegmentCacheManager wherever possible. There is no change in the functionality.
