* SQL: Allow NULLs in place of optional arguments in many functions.
Also adjust SQL docs to describe how to make time literals using
TIME_PARSE (which is now possible in a nicer way).
* Be less forbidden.
* Upgrade various build and doc links to https.
Where it wasn't possible to upgrade build-time dependencies to https,
I kept http in place but used hardcoded checksums or GPG keys to ensure
that artifacts fetched over http are verified properly.
* Switch to https://apache.org.
* update sys.servers table to show all servers
* update docs

* add postgresql meta db table schema configuration property (#7137)

values.
You do not need to set it if there is no change from the default schema
'public'.

* 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.
* V1 - improve parallelism of zookeeper based segment change processing
* Create zk nodes in batches. Address code review comments.
Introduce various configs.
* Add documentation for the newly added configs
* Fix test failures
* 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
* Fix NPE in test
* Remove documentation for configs that are no longer needed
* Address code review comments
* Address more code review comments
* Fix checkstyle issue
* Address code review comments
* Code review comments
* Add back monitor node remove executor
* Cleanup code to isolate null checks and minor refactoring
* Change param name since it conflicts with member variable name
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.

Removes the coordinator sanity check that prevents it from dropping all
segments. It's useful to get rid of this, since the behavior is
unintuitive for dev/testing clusters where users might regularly want
to drop all their data to get back to a clean slate.
But the sanity check was there for a reason: to prevent a race condition
where the coordinator might drop all segments if it ran before the
first metadata store poll finished. This patch addresses that concern
differently, by allowing methods in MetadataSegmentManager to return
null if a poll has not happened yet, and canceling coordinator runs
in that case.
This patch also makes the "dataSources" reference in
SQLMetadataSegmentManager volatile. I'm not sure why it wasn't volatile
before, but it seems necessary to me: it's not final, and it's dereferenced
from multiple threads without synchronization.
