Renamed 'Generic Column' -> 'Numeric Column'; Fixed a few resource leaks in processing; misc refinements (#5957)
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`

Gian Merlino 3548396a45 SQL: Update to Calcite 1.17.0. (#6404)
* 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.

bolkedebruin 8f07a39af7 Skip OS cache on Linux when pulling segments (#5421)
Druid relies on the page cache of Linux in order to have memory segments.
However when loading segments from deep storage or rebalancing the page
cache can get poisoned by segments that should not be in memory yet.
This can significantly slow down Druid in case rebalancing happens
as data that might not be queried often is suddenly in the page cache.

This PR implements the same logic as is in Apache Cassandra and Apache
Bookkeeper.

Closes #4746

Gian Merlino b20e3038b6 SQL: Upgrade to Calcite 1.14.0, some refactoring of internals. (#4889)
* 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.

* Add missing @Override annotation.

* Adjustments for forbidden APIs.

Gian Merlino 2ce8123bdb Move scan-query from a contrib extension into core. (#4751)
* Move scan-query from a contrib extension into core.

Based on a proposal at: https://groups.google.com/d/topic/druid-development/ME_OatUDnbk/discussion

This patch also adds support for virtual columns to the Scan query,
and updates Druid SQL to use Scan instead of Select.

This patch also makes some behavioral changes to handling of the __time
column. In particular, it is now is returned as "__time" rather than
"timestamp"; it is no longer included if you do not specifically ask for
it in your "columns"; and it is returned as a long rather than a string.

Users can revert time handling to the legacy extension behavior by
setting "legacy" : true in their queries, or setting the property
druid.query.scan.legacy = true. This is meant to provide a migration
path for users that were formerly using the contrib extension.

* Adjustments from review.

* Add back Select query.

* Adjust SQL docs.

* Restore SelectQuery link.

Gian Merlino 16817e408d SQL + Expressions = Best friends forever. (#4360)
* SQL + Expressions = Best friends forever.

- Use expressions as a projection layer for anything that can't be
  expressed using traditional Druid extractionFns. Sometimes they're
  embedded directly (like "expression" filters, builtin aggregators,
  or "expression" post-aggregators). Sometimes they're referenced
  through virtual columns (like dimensionSpecs, which can't innately
  reference functions of more than one column without the virtual
  column layer).
- Add many new functions and operators, taking advantage of the
  expression capability (see the querying/sql.md doc).
- Improve consistency of constant reduction and of casting by
  using Druid expressions for this instead of Calcite's RexExecutor.

* Fix casting bug, and other code review comments.

* Fix docs.

Charles Allen 8024b915e2 [QTL] Implement LookupExtractorFactory of namespaced lookup (#2926)
* support LookupReferencesManager registration of namespaced lookup and eliminate static configurations for lookup from namespecd lookup extensions

- druid-namespace-lookup and druid-kafka-extraction-namespace are modified
- However, druid-namespace-lookup still has configuration about ON/OFF
  HEAP cache manager selection, which is not namespace wide
  configuration but node wide configuration as multiple namespace shares
  the same cache manager

* update KafkaExtractionNamespaceTest to reflect argument signature changes

* Add more synchronization functionality to NamespaceLookupExtractorFactory

* Remove old way of using extraction namespaces

* resolve compile error by supporting LookupIntrospectHandler

* Remove kafka lookups

* Remove unused stuff

* Fix start and stop behavior to be consistent with new javadocs

* Remove unused strings

* Add timeout option

* Address comments on configurations and improve docs

* Add more options and update hash key and replaces

* Move monitoring to the overriding classes

* Add better start/stop logging

* Remove old docs about namespace names

* Fix bad comma

* Add `@JsonIgnore` to lookup factory

* Address code review comments

* Remove ExtractionNamespace from module json registration

* Fix problems with naming and initialization. Add tests

* Optimize imports / reformat

* Fix future not being properly cancelled on failed initial scheduling

* Fix delete returns

* Add more docs about whole introspection

* Add `/version` introspection point for lookups

* Add more tests and address comments

* Add StaticMap extraction namespace for testing. Also add a bunch of tests

* Move cache system property to `druid.lookup.namespace.cache.type`

* Make VERSION lower case

* Change poll period to 0ms  for StaticMap

* Move cache key to bytebuffer

* Change hashCode and equals on static map extraction fn

* Add more comments on StaticMap

* Address comments

* Make scheduleAndWait use a latch

* Sanity renames and fix imports

* Remove extra info in docs

* Fix review comments

* Strengthen failure on start from warn to error

* Address comments

* Rename namespace-lookup to lookups-cached-global

Xavier Léauté e79284da59 new interval based cost function (#2972)
* new interval based cost function

Addresses issues with balancing of segments in the existing cost function
- `gapPenalty` led to clusters of segments ~30 days apart
- `recencyPenalty` caused imbalance among recent segments
- size-based cost could be skewed by compression

New cost function is purely based on segment intervals:
- assumes each time-slice of a partition is a constant cost
- cost is additive, i.e. cost(A, B union C) = cost(A, B) + cost(A, C)
- cost decays exponentially based on distance between time-slices

* comments and formatting

* add more comments to explain the calculation

Gian Merlino 977e867ad8 Downgrade geoip2, exclude com.google.http-client.
Reverts "Update com.maxmind.geoip2 to 2.6.0" and exclude the google http client
from com.maxmind.geoip2. This should satisfy the original need from #2646 (wanting
to run Druid along with an upgraded com.google.http-client) while preventing
Jackson conflicts pointed out in #2717.

Fixes #2717.

This reverts commit 21b7572533.

Erik Dubbelboer 21b7572533 Update com.maxmind.geoip2 to 2.6.0
com.maxmind.geoip2 2.6.0 depends on com.google.http-client 1.15.0-rc (3 years old).
When trying to include other libraries in Druid that require an up to date version of com.google.http-client this causes a problem.

Gian Merlino f22fb2c2cf KafkaIndexTask.
Reads a specific offset range from specific partitions, and can use dataSource metadata
transactions to guarantee exactly-once ingestion.

Each task has a finite lifecycle, so it is expected that some process will be supervising
existing tasks and creating new ones when needed.
