* Expressions: Fix improper supplier reuse with missing columns.
ExpressionSelectors has an optimization that skips building a Map
when there is only one input supplier. However, this optimization
should not be used in the case where the is one input supplier but
more than one input identifier (which can happen when only one
input identifier corresponds to an actual column).
Fixes#6556.
* Add underscores to statics.
* SQL: Set INFORMATION_SCHEMA catalog name to "druid".
Some third party tools ignore catalogs with empty names. So using
the name "druid" for the catalog makes integration easier.
* Update tests.
Also add a "fromIndex" argument to the strpos expression function. There
are some -1 and +1 adjustment terms due to the fact that the strpos
expression behaves like Java indexOf (0-indexed), but the POSITION SQL
function is 1-indexed.
* Optimization for expressions that hit a single long column.
There was previously a single-long-input optimization that applied only
to the time column. These have been combined together. Also adds
type-specific value caching to ExprEval, which allowed simplifying
the SingleLongInputCachingExpressionColumnValueSelector code.
* Add more benchmarks.
* Don't use LRU cache for __time.
* Simplify a bit.
* Let the cache grow.
* use BloomFilter instead of BloomKFilter since the latters test method is not threadsafe
* fix formatting
* style and forbidden api
* remove redundant hive notice entry
* add todo with note to delete copied implementation and link to related hive jira
* better fix for masks than ThreadLocal
* Use current coordinator leader instead of cached one (#6551)
Check the response status and throw exception if not OK
* Modify tests
* PR comment
* Add the correct check for status of BytesAccumulatingResponseHandler
* Move the status check into JsonParserIterator so sql query outputs meaningful message on failure
* Fix tests
* move parquet-extensions from contrib to core, adds new hadoop parquet parser that does not convert to avro first and supports flattenSpec and int96 columns, add support for flattenSpec for parquet-avro conversion parser, much test with a bunch of files lifted from spark-sql
* fix avro flattener to support nullable primitives for auto discovery and now only supports primitive arrays instead of all arrays
* remove leftover print
* convert micro timestamp to millis
* checkstyle
* add ignore for .parquet and .parq to rat exclude
* fix legit test failure from avro flattern behavior change
* fix rebase
* add exclusions to pom to cut down on redundant jars
* refactor tests, add support for unwrapping lists for parquet-avro, review comments
* more comment
* fix oops
* tweak parquet-avro list handling
* more docs
* fix style
* grr styles
* Period load/drop/broadcast rules should include the future by default
* address comments
* adjust coordinator console and tweak docs
* address comments
* fix travis-ci
This PR allows to control the fields in `RequestLogEvent`, emitted in `EmittingRequestLogger`. In our case, we want to get rid of the `intervals` fields of the query objects that are a part of `DefaultRequestLogEvent`. They are enormous (thousands of segments) and not useful.
Related to #5522, FYI @a2l007.
* Prohibit some guava collection APIs and use JDK APIs directly
* reset files that changed by accident
* sort codestyle/druid-forbidden-apis.txt alphabetically
* 1. Mysql default transaction isolation is REPEATABLE_READ, treat it as READ_COMMITTED will reduce insert id conflict.
2. Add an index to 'dataSource used end' is work well for the most of scenarios(get recently segments), and it will speed up sync add pending segments in DB.
3. 'select and insert' is not need within transaction.
* Use TaskLockbox.doInCriticalSection instead of synchronized syntax to speed up insert pending segments.
* fix typo for NullPointerException
* remove consumer.listTopics() method
* add consumerLock and exception handling for consumer.partitionFor() and remove some useless checks
* add check in case consumer.partitionsFor() returns null
* fix CI failure
* fix failed UT
* Revert "fix CI failure"
This reverts commit f839d09e1e.
* revert unless commit and re-commit the useful part to fix failed UT
* use a sha512 hash of bloom filter for cache key instead of filter bytes
* make serde private, BloomDimFilter.toString and BloomDimFilter.equals use hash instead of bloomKFilter which has no tostring or equals of its own
* keep and use HashCode object instead of converting to bytes up front
* uneeded imports oops
* tweaks from review
* refactor dupe code
* refactor
* include mysql-metadata-storage extension in distribution, but without the GPL-licensed connector library
* Install mysql connector package
* use symlinks to avoid versioning issues
* add documentation for fetching the mysql connector
