* QueryableIndexStorageAdapter: Lift column cache to Cursor sequence.
This is where it was before #4710, when its was moved to the individual
Cursors, leading to higher than expected memory usage. It could be
extreme for finer query granularities like "second".
* Comment.
* SQL: Upgrade to Calcite 1.14.0, some refactoring of internals.
This brings benefits:
- Ability to do GROUP BY and ORDER BY with ordinals.
- Ability to support IN filters beyond 19 elements (fixes#4203).
Some refactoring of druid-sql internals:
- Builtin aggregators and operators are implemented as SqlAggregators
and SqlOperatorConversions rather being special cases. This simplifies
the Expressions and GroupByRules code, which were becoming complex.
- SqlAggregator implementations are no longer responsible for filtering.
Added new functions:
- Expressions: strpos.
- SQL: TRUNCATE, TRUNC, LENGTH, CHAR_LENGTH, STRLEN, STRPOS, SUBSTR,
and DATE_TRUNC.

* Also handle case when intervals are already present
* Fix checkstyle error
* Use factory method instead for Datetime
* Use Intervals factory method
"No worker selection strategy set." would get logged any time tryAssignTask runs
in the default configuration, which is often. It also doesn't provide much value.
* Make AutoScaler, ProvisioningStrategy and BaseWorkerBehaviorConfig extension points; More logging in PendingTaskBasedWorkerProvisioningStrategy
* Address comments and fix a bug
* Extract method
* debug logging
* Rename BaseWorkerBehaviorConfig to WorkerBehaviorConfig and WorkerBehaviorConfig to DefaultWorkerBehaviorConfig
* Fixes
* Priority on loading for primary replica
* Simplicity fixes
* Fix on skipping drop for quick return.
* change to debug logging for no replicants.
* Fix on filter logic
* swapping if-else
* Fix on wrong "hasTier" logic
* Refactoring of LoadRule
* Rename createPredicate to createLoadQueueSizeLimitingPredicate
* Rename getHolderList to getFilteredHolders
* remove varargs
* extract out currentReplicantsInTier
* rename holders to holdersInTier
* don't do temporary removal of tier.
* rename primaryTier to tierToSkip
* change LinkedList to ArrayList
* Change MinMaxPriorityQueue in DruidCluster to TreeSet.
* Adding some comments.
* Modify log messages in light of predicates.
* Add in-method comments
* Don't create new Object2IntOpenHashMap for each run() call.
* Cache result from strategy call in the primary assignment to be reused during the same run.
* Spelling mistake
* Cleaning up javadoc.
* refactor out loading in progress check.
* Removed redundant comment.
* Removed forbidden API
* Correct non-forbidden API.
* Precision in variable type for NavigableSet.
* Obsolete comment.
* Clarity in method call and moving retrieval of ServerHolder into method call.
* Comment on mutability of CoordinatoorStats.
* Added auxiliary fixture for dropping.
* Add identity to query metrics, logs.
Also fix a bug where unauthorized requests would not emit any logs or metrics,
and instead would log a "Tried to emit logs and metrics twice" warning.
Also rename QueryResource's "getServer" to "cancelQuery", because that's what
it does.
* Do not emit identity by default.
* SQL: Delay query translation until the end of planning.
This fixes a bug in which input rels to nested queries could get swapped
out by the optimizer, leading to incorrect nested query planning.
This also, I hope, makes the query translation code easier to understand. At
least for me, the PartialDruidQuery -> DruidQuery -> Query chain is easier
to understand than the previous-existing rule spaghetti.
* Make test more consistent.
* Fix test.
* remove ServerConfig from DruidNode as all information needs to be present in DruidNode serialized form
* sanitize output of /druid/coordinator/v1/cluster endpoint
* Added org.joda.time.DateTime#(java.lang.String) to forbidden API.
* Added org.joda.time.DateTime#(java.lang.String, org.joda.time.format.DateTimeFormatter) to forbidden API.
* Add additional APIs that may create DateTime with default time zone
* Add helper function that accepts formatter to parse String.
* Add additional forbidden APIs
* Replace existing usage of forbidden APIs
* Use wrapper class to enforce Chronology on DateTimeFormatter.
* Creates constant UtcFormatter for constant ISODateTimeFormat.
