Surekha 13c616ba24 'maxBytesInMemory' tuningConfig introduced for ingestion tasks (#5583)
* This commit introduces a new tuning config called 'maxBytesInMemory' for ingestion tasks

Currently a config called 'maxRowsInMemory' is present which affects how much memory gets
used for indexing.If this value is not optimal for your JVM heap size, it could lead
to OutOfMemoryError sometimes. A lower value will lead to frequent persists which might
be bad for query performance and a higher value will limit number of persists but require
more jvm heap space and could lead to OOM.
'maxBytesInMemory' is an attempt to solve this problem. It limits the total number of bytes
kept in memory before persisting.

 * The default value is 1/3(Runtime.maxMemory())
 * To maintain the current behaviour set 'maxBytesInMemory' to -1
 * If both 'maxRowsInMemory' and 'maxBytesInMemory' are present, both of them
   will be respected i.e. the first one to go above threshold will trigger persist

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.

Gian Merlino bf8fd4c203 Add flattenSpec support to the Avro parser. (#4832)
* Add flattenSpec support to the Avro parser.

Also:

- Refactor the JSONPathParser a bit so it can share flattening code
  with Avro (see ObjectFlatteners).
- Remove the JSONParser. It was only used in two places: by
  UriNamespaceExtractor, and as a base for JSONToLowerParser. Migrated
  the former to JSONPathParser and made the latter a standalone.
- Move GenericRecordAsMap to the Parquet extension, since the Avro
  extension no longer uses it.

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.

Fokko Driesprong ff501e8f13 Add Date support to the parquet reader (#4423)
* Add Date support to the parquet reader

Add support for the Date logical type. Currently this is not supported. Since the parquet
date is number of days since epoch gets interpreted as seconds since epoch, it will fails
on indexing the data because it will not map to the appriopriate bucket.

* Cleaned up code and tests

Got rid of unused json files in the examples, cleaned up the tests by
using try-with-resources. Now get the filenames from the json file
instead of hard coding them and integrated general improvements from
the feedback provided by leventov.

* Got rid of the caching

Remove the caching of the logical type of the time dimension column
and cleaned up the code a bit.

Gian Merlino dbdfcd2443 Fix extension reference in Kafka namespaced lookup docs.
The reference to io.druid.extensions:kafka-extraction-namespace is wrong (should
be druid-kafka-extraction-namespace) and unnecessary (the extension id is written
at the top of the doc file).
