This PR accumulates many refactorings and small improvements that I did while preparing the next change set of https://github.com/druid-io/druid/projects/2. I finally decided to make them a separate PR to minimize the volume of the main PR.
Some of the changes:
- Renamed confusing "Generic Column" term to "Numeric Column" (what it actually implies) in many class names.
- Generified `ComplexMetricExtractor`
* Replace statusCode with status (#6333)
Also changed runnerStatusCode to runnerStatus to keep things consistent
* Add unit test
* Add status param to TaskStatusPlus
Revert to statusCode and runnerStatusCode
* Add additional status member to TaskStatusPlus
* Change TaskResponseObject to match overlord's response object
* Address PR comments
* address comments
* Add runtime exception after logging error
* Remove (deprecated)status member variable from TaskStatusPlus
* Minor change
* ITTLSTest: Retry on "Connection reset by peer".
This sometimes happens and causes tests to fail spuriously.
* Better error messages when retries are exhausted.
* SQL: Update to Calcite 1.17.0.
Other than keeping things fresh, another motivation is that
this fixes CALCITE-1436 (AggregateNode NPE for aggregators other
than SUM/COUNT), which affects aggregate functions on our system
tables.
Also sets shouldConvertRaggedUnionTypesToVarying = true, a new
type system parameter that prefers VARCHAR over CHAR. This is
better for Druid, because we don't really have support for a
true CHAR type.
* Remove unused import.
* Added backpressure metric
* Updated channelReadable to AtomicBoolean and fixed broken test
* Moved backpressure metric logic to NettyHttpClient
* Fix placement of calculating backPressureDuration
The "Duplicate field name" check on inputRowSignature is too strict:
it is actually fine for a row signature to have the same field name
twice. It happens when the same expression is selected twice, and
both selections map to the same Druid object (dimension, aggregator,
etc).
I did not succeed in writing a test that triggers this, but I did see
it occur in production for a complex query with hundreds of aggregators.
* Add support targetCompactionSizeBytes for compactionTask
* fix test
* fix a bug in keepSegmentGranularity
* fix wrong noinspection comment
* address comments
The indexes introduced in #6348 were on the wrong table. The tests
did not catch them due to retries on the create table steps (the
first try created the table but not the bogus indexes; the second
try noticed that the table already existed and did nothing). This
patch doesn't fix the issue with the tests, since the best way to
do that would be to do the table and index creation in a
transaction; but, this is not supported by all of our supported
database engines.
