BaseNodeRoleWatcher counts down cacheInitialized after a timeout, but also sets some flag that it was a timed-out initialization. and call nodeViewInitializationTimedOut (new method on listeners) instead of nodeViewInitialized. Then listeners can do what is most appropriate with this information.

the test has 593 cases; however there are quite a few parameterized
from the 107 methods annotated with @Test - 42 is not yet working
* replace the isRoot hack in DruidQueryGenerator with a logic that instead looks ahead for the next node; and doesn't let the previous node do the Project - this makes it plan more likely than the existing planner

* `Expr#singleThreaded` which creates a singleThreaded version of the actual expression (caching ExprEval is allowed)
* `Expr#makeSingleThreaded` to make a whole subtree of expressions 'singleThreaded' - uses `Shuttle` to create the new expression tree
* `ConstantExpr#singleThreaded` creates a specialized `ConstantExpr` which does cache the `ExprEval`
* some `@Immutable` annotations were added to make it more likely to notice that there might be something off if a similar change will be made around here for some reason
Since #15175, the javadoc for ReadableFieldPointer is somewhat out of date. It says that
the pointer only points to the beginning of the field, but this is no longer true. This
patch updates the javadoc to be more accurate.
allow a hashjoin result to be converted to RowsAndColumns
added StorageAdapterRowsAndColumns
fix incorrect isConcrete() return values during early phase of planning
Running npm run build, you should no longer get the message:
[ERROR] Invalid docusaurus-theme-mermaid version 2.4.3.
All official @docusaurus/* packages should have the exact same version as @docusaurus/core (2.4.1).
Maybe you want to check, or regenerate your yarn.lock or package-lock.json file?
yarn build didn't have the same issue, and yarn install did not generate a new yarn.lock
* Add support for AzureDNSZone enabled storage accounts used for deep storage
Added a new config to AzureAccountConfig
`storageAccountEndpointSuffix`
which allows the user to specify a storage account endpoint suffix where the underlying
storage account is enabled for AzureDNSZone. The previous config `endpointSuffix`, did not allow
support for such accounts. The previous config has been deprecated in favor of this new config. Also
fixed an issue where `managedIdentityClientId` was not being set properly
* * address review comments
* * add back azure government link and docs
* Move retries into DataSegmentPusher implementations.
The individual implementations know better when they should and should
not retry. They can also generate better error messages.
The inspiration for this patch was a situation where EntityTooLarge was
generated by the S3DataSegmentPusher, and retried uselessly by the
retry harness in PartialSegmentMergeTask.
* Fix missing var.
* Adjust imports.
* Tests, comments, style.
* Remove unused import.
* Rows.objectToNumber: Accept decimals with output type LONG.
PR #15615 added an optimization to avoid parsing numbers twice in cases
where we know that they should definitely be longs or
definitely be doubles. Rather than try parsing as long first, and then
try parsing as double, it would use only the parsing routine specific to
the requested outputType.
This caused a bug: previously, we would accept decimals like "1.0" or
"1.23" as longs, by truncating them to "1". After that patch, we would
treat such decimals as nulls when the outputType is set to LONG.
This patch retains the short-circuit for doubles: if outputType is
DOUBLE, we only parse the string as a double. But for outputType LONG,
this patch restores the old behavior: try to parse as long first,
then double.
Updated the Direct Druid Client so as to make Connection Count Server Selector Strategy work more efficiently.
If creating connection to a node is slow, then that slowness wouldn't be accounted for if we count the open connections after sending the request. So we increment the counter and then send the request.

* MSQ: Nicer error when sortMerge join falls back to broadcast.
In certain cases, joins run as broadcast even when the user hinted
that they wanted sortMerge. This happens when the sortMerge algorithm
is unable to process the join, because it isn't a direct comparison
between two fields on the LHS and RHS.
When this happens, the error message from BroadcastTablesTooLargeFault
is quite confusing, since it mentions that you should try sortMerge
to fix it. But the user may have already configured sortMerge.
This patch fixes it by having two error messages, based on whether
broadcast join was used as a primary selection or as a fallback selection.
* Style.
* Better message.
* cooler cursor filter processing allowing much smart utilization of indexes by feeding selectivity forward, with implementations for range and predicate based filters
* added new method Filter.makeFilterBundle which cursors use to get indexes and matchers for building offsets
* AND filter partitioning is now pushed all the way down, even to nested AND filters
* vector engine now uses same indexed base value matcher strategy for OR filters which partially support indexes
Currently, while reading results from realtime tasks, requests are sent on a segment level. This is slightly wasteful, as when contacting a data servers, it is possible to transfer results for all segments which it is hosting, instead of only one segment at a time.
One change this PR makes is to group the segments on the basis of servers. This reduces the number of queries to data servers made. Since we don't have access to the number of rows for realtime segments, the grouping is done with a fixed estimated number of rows for each realtime segment.
* Update basic-cluster-tuning.md
The sentence "When free system memory is greater than or equal to druid.segmentCache.locations, the more segment data the Historical can be held in the memory-mapped segment cache" didn't read well. Updated to clarify it.
* Update docs/operations/basic-cluster-tuning.md

* All segments stored in the same batch have the same created_date entry.
In the absence of a group_id column, this metadata would allow us to easily
reason about and troubleshoot ingestion-related issues.
* Rename metric name and code references to eligibleUnusedSegments.
Address review comment from https://github.com/apache/druid/pull/15941#discussion_r1503631992
* Kill duty and test improvements.
Initial commit with:
- Bug fixes - auto-kill can throw NPE when there are no datasources present and defaults mismatch.
- Add new stat for candidate segment intervals killed.
- Move a couple of debug logs to info logs for improved visibility (should only log once per kill period).
- Remove redundant checks for code readability.
- Updated tests from using mocks (also the mocks weren't using last updated timestamp) and
add more test coverage for different config parameters.
- Add a couple of unit tests that are ignored for the eternity case to prove that
the kill duty doesn't clean up segments with ALL grain or that end in DateTimes.MAX.
- Migrate Druid exception from user to operator persona.
* Address review comments.
* Remove unused methods.
* fix up format specifier and validate bad config tests.
* Consolidate the helpers a bit more and add another test.
* Update test names. Add javadoc placeholders for slightly involved tests.
* Add docs for metric kill/candidateUnusedSegments/count.
Also, rename to disambiguate.
* Comments.
* Apply logging suggestions from code review

* Review comments
- Clarify docs on eligibility.
- Add test for multiple segments in the same interval. Clarify comment.
- Remove log line from test.
- Remove lastUpdatedDate = now.plus(10) from test.
* minor cleanup.
* Clarify javadocs for getUnusedSegmentIntervals().

The code in the groupBy engine and the topN engine assume that the dimensions are comparable and can call dimA.compareTo(dimB) to sort the dimensions and group them together.
This works well for the primitive dimensions, because they are Comparable, however falls apart when the dimensions can be arrays (or in future scenarios complex columns). In cases when the dimensions are not comparable, Druid resorts to having a wrapper type ComparableStringArray and ComparableList, which is a Comparable, based on the list comparator.
* Fix up typos, inaccuracies and clean up code related to PARTITIONED BY.
* Remove wrapper function and update tests to use DruidExceptionMatcher.
* Checkstyle and Intellij inspection fixes.
This PR creates symlinks when there are duplicate jars present in the extension. Docker image includes contrib extensions, too, and the size of the image has bloated up quite a lot of late. This change also fixes "ITNestedQueryPushDownTest integration test"
