Lookups: Inherit "injective" from registered lookups, improve docs. (#5316)
Code changes:
- In the lookup-based extractionFns, inherit injective property from
  the lookup itself if not specified.

Doc changes:
- Add a "Query execution" section to the lookups doc explaining how
  injective lookups and their optimizations work.
- Remove scary warnings against using registeredLookup extractionFns.
  They are necessary and important since they work with filters and
  function cascades -- two things that the dimension specs do not do.
  They deserve to be first class citizens.
- Move the "registeredLookup" fn above the "lookup" fn. It's probably
  more commonly used, so the docs read better this way.

Peter Cunningham ede7cf9eef Added support for where clauses to JDBC lookups. (#4643)
* Added support for where clauses to filter lookup values on ingestion.

Added a filter field to the JDBC lookups that is used to generate a
where clause so that only rows matching the filter value will be
brought into Druid. Example being filter="SOMECOLUMN=1"

* Required changes based on code review.

Gian Merlino 4203580290 URIExtractionNamespace: Treat null values in lookup maps as missing entries. (#3512)
* URIExtractionNamespace: Treat null values in lookup maps as missing entries.

This is useful when many logical lookups are derived from the same base JSON file,
and some lookups' values may be unknown sometimes.

* Add test, logging message, and address other comments.

* Update 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

* resolve compile error by supporting LookupIntrospectHandler

* Remove kafka lookups
