* Remove SQL experimental banner and other doc adjustments.
Also,
- Adjust the ToC and other docs a bit so SQL and native queries are
presented on more equal footing.
- De-emphasize querying historicals and peons directly in the
native query docs. This is a really niche thing and may have been
confusing to include prominently in the very first paragraph.
- Remove DataSketches and Kafka indexing service from the experimental
features ToC. They are not experimental any longer and were there in
error.
* More notes.
* Slight tweak.
* Remove extra extra word.
* Remove RT node from ToC.

* Fix more test failures
* Remove prinstacktrace statements
* Address code review comments
* Use a single queue
* Address code review comments
Since we have a separate load peon for every historical, just having a single SegmentChangeProcessor
task per historical is enough. This commit also gets rid of the associated config druid.coordinator.loadqueuepeon.curator.numCreateThreads
* Resolve merge conflict
* Fix compilation failure
* Remove batching since we already have a dynamic config maxSegmentsInNodeLoadingQueue that provides that control

* sampler initial check-in
fix checkstyle issues
add sampler fix to process CSV files from cache properly
change to composition and rename some classes
add tests and report num rows read and indexed
remove excludedByFilter flag and don't send filtered out data
fix tests to handle both settings for druid.generic.useDefaultValueForNull
* wrap sampler firehose in TimedShutoffFirehoseFactory to support timeouts
* code review changes - add additional comments, limit maxRows
* EmitterModule: Throw an error on invalid emitter types.
The current behavior of silently using the "noop" emitter is unhelpful
and makes it difficult to debug config typos.
* Add comments.
* BaseAppenderatorDriver: Fix potentially overeager segment cleanup.
Here is a thing that I think can go wrong:
1. We push some segments, then try to publish them transactionally.
2. The segments are actually published, but the 200 OK response gets
lost (connection dropped, whatever).
3. We try again, and on the second try, the publish fails (because
the transaction baseline start metadata no longer matches).
4. Because the publish failed, we delete the pushed segments.
5. But this is bad, because the publish didn't really fail, it actually
succeeded in step 2.
I haven't seen this in the wild, but thought about it while
reviewing #7537.
This patch also cleans up logging a bit, making it more accurate and
somewhat less chatty.
* Avoid wrapping exceptions when not necessary.
* Java 9 compatible specialized class compilation
We currently use Unsafe.defineClass to compile specialized classes,
which has been removed in Java 9 and above. This change switches to
MethodHandles.Lookup.defineClass at runtime, which provides similar
functionality in newer JDK versions.
* add comments
* fix incorrect comment
* add unsafe utility class
* make comments java-doc style
* fix checkstyle errors
* rename unsafe -> unsafeutil
* move defineClass method to utility class
* rename unsafeutil -> unsafeutils to match other utility class names
* remove extra lookup method
* add utiliy class docs
* more comments
* minor comments and formatting
This feature allows Calcite's Bindable interpreter to be bolted on
top of Druid queries and table scans. I think it should be removed for
a few reasons:
1. It is not recommended for production anyway, because it generates
unscalable query plans (e.g. it will plan a join into two table scans
and then try to do the entire join in memory on the broker).
2. It doesn't work with Druid-specific SQL functions, like TIME_FLOOR,
REGEXP_EXTRACT, APPROX_COUNT_DISTINCT, etc.
3. It makes the SQL planning code needlessly complicated.
With SQL coming out of experimental status soon, it's a good opportunity
to remove this feature.
