changes:
* long and double value columns are now written directly, at the same time as writing out the 'intermediary' dictionaryid column with unsorted ids
* remove reverse value lookup from GlobalDictionaryIdLookup since it is no longer needed
* fix bug in /status/properties filtering
* Refactor tests to use jackson for parsing druid.server.hiddenProperties instead of hacky string modifications
* make javadoc more descriptive using example
* add in a sanity assertion that raw properties keyset size is greater than filtered properties keyset size
* MSQ extension: Fix over-capacity write in ScanQueryFrameProcessor.
Frame processors are meant to write only one output frame per cycle.
The ScanQueryFrameProcessor would write two when reading from a channel
if the input frame cursor cycled and then the output frame filled up
while reading from the next frame.
This patch fixes the bug, and adds a test. It also makes some adjustments
to the processor code in order to make it easier to test.
* Add license header.
* Add interpolation to JsonConfigurator
* Fix checkstyle
* Fix tests by removing common-text override
* Add back commons-text without version
* Remove unused hadoopDir configs
* Move some stuff to hopefully pass coverage
* more consistent expression error messages
* review stuff
* add NamedFunction for Function, ApplyFunction, and ExprMacro to share common stuff
* fixes
* add expression transform name to transformer failure, better parse_json error messaging
-Add classes for writing cell values in LZ4 block compressed format.
Payloads are indexed by element number for efficient random lookup
-update SerializablePairLongStringComplexMetricSerde to use block
compression
-SerializablePairLongStringComplexMetricSerde also uses delta encoding
of the Long by doing 2-pass encoding: buffers first to find min/max
numbers and delta-encodes as integers if possible
Entry points for doing block-compressed storage of byte[] payloads
are the CellWriter and CellReader class. See
SerializablePairLongStringComplexMetricSerde for how these are used
along with how to do full column-based storage (delta encoding here)
which includes 2-pass encoding to compute a column header

Compressed Big Decimal is an extension which provides support for
Mutable big decimal value that can be used to accumulate values
without losing precision or reallocating memory. This type helps in
absolute precision arithmetic on large numbers in applications,
where greater level of accuracy is required, such as financial
applications, currency based transactions. This helps avoid rounding
issues where in potentially large amount of money can be lost.
Accumulation requires that the two numbers have the same scale,
but does not require that they are of the same size. If the value
being accumulated has a larger underlying array than this value
(the result), then the higher order bits are dropped, similar to what
happens when adding a long to an int and storing the result in an
int. A compressed big decimal that holds its data with an embedded
array.
Compressed big decimal is an absolute number based complex type
based on big decimal in Java. This supports all the functionalities
supported by Java Big Decimal. Java Big Decimal is not mutable in
order to avoid big garbage collection issues. Compressed big decimal
is needed to mutate the value in the accumulator.

Two improvements:
- Use a realistic targetRowsPerSegment, so if people copy and paste
the example from the docs, it will generate reasonable segments.
- Spell "countryName" correctly.
The docs say Java 17 support is experimental, and give tips on running
successfully with Java 17.
This patch also removes java.base/jdk.internal.perf and
jdk.management/com.sun.management.internal from the list of required
exports and opens, because they were formerly needed for JvmMonitor,
which was rewritten in #12481 to use MXBeans instead.
* FrameFile: Java 17 compatibility.
DataSketches Memory.map is not Java 17 compatible, and from discussions
with the team, is challenging to make compatible with 17 while also
retaining compatibility with 8 and 11. So, in this patch, we switch away
from Memory.map and instead use the builtin JDK mmap functionality. Since
it only supports maps up to Integer.MAX_VALUE, we also implement windowing
in FrameFile, such that we can still handle large files.
Other changes:
1) Add two new "map" functions to FileUtils, which we use in this patch.
2) Add a footer checksum to the FrameFile format. Individual frames
already have checksums, but the footer was missing one.
* Changes for static analysis.
* wip
* Fixes.
* Building druid-it-tools and running for travis in it.sh
* Addressing comments
* Updating druid-it-image pom to point to correct it-tools
* Updating all it-tools references to druid-it-tools
* Adding dist back to it.sh travis
* Trigger Build
* Disabling batchIndex tests and commenting out user specific code
* Fixing checkstyle and intellij inspection errors
* Replacing tabs with spaces in it.sh
* Enabling old batch index tests with indexer
* Fix accounting of bytesAdded in ReadableByteChunksFrameChannel.
Could cause WorkerInputChannelFactory to get into an infinite loop when
reading the footer of a frame file.
* Additional tests.
This dependency was no longer needed after #12481, but remained because
it was used for a (now useless) test. This patch removes the test and
the dependency.
Two changes:
1) Restore the text of the SQL query. It was removed in #12897, but
then it was later pointed out that the text is helpful for end
users querying Druid through tools that do not show the SQL queries
that they are making.
2) Adjust wording slightly, from "Cannot build plan for query" to
"Query not supported". This will be clearer to most users. Generally
the reason we get these errors is due to unsupported SQL constructs.
During ingestion, if a row containing multiple values for a numeric dimension is encountered,
the whole ingestion task fails. Ideally, this should just be registered as a parse exception.
Changes:
- Remove `instanceof List` check from `LongDimensionIndexer`, `FloatDimensionIndexer` and `DoubleDimensionIndexer`.
Any invalid type, including list, throws a parse exception in `DimensionHandlerUtils.convertObjectToXXX`
methods. `ParseException` is already handled in `OnHeapIncrementalIndex` and does not fail the entire task.
* json_value adjustments
changes:
* native json_value expression now has optional 3rd argument to specify type, which will cast all values to the specified type
* rework how JSON_VALUE is wired up in SQL. Now we are using a custom convertlet to translate JSON_VALUE(... RETURNING type) into dedicated JSON_VALUE_BIGINT, JSON_VALUE_DOUBLE, JSON_VALUE_VARCHAR, JSON_VALUE_ANY instead of using the calcite StandardConvertletTable that wraps JSON_VALUE_ANY in a CAST, so that we preserve the typing of JSON_VALUE to pass down to the native expression as the 3rd argument
* fix json_value_any to be usable by humans too, coverage
* fix bug
* checkstyle
* checkstyle
* review stuff
* validate that options to json_value are the supported options rather than ignore them
* remove more legacy undocumented functions
* KLL sketch
* added documentation
* direct static refs
* direct static refs
* fixed test
* addressed review points
* added KLL sketch related terms
* return a copy from get
* Copy unions when returning them from "get".
* Remove redundant "final".
