* Also better lookup docs
* Fix test timeouts
* Fix timing of deserialized test
* Fix problem with 0 wait failing immediately
* validate X-Druid-Task-Id header in request and add header to response

- 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

* Make URI Exctraction Namespace take more sane arguments
* Fixes https://github.com/druid-io/druid/issues/2669
* Update docs
* Rename error message
* Undo overzealous deletion of docs
* Explain caching mechanism a bit more in docs
* Move kafka-extraction-namespace to the Lookup framework.
* Address comments
* Fix missing kafka introspection
* Fix tests to be less racy
* Make testing a bit more leniant
* Make tests even more forgiving
* Add comments to kafka lookup cache method
* Move startStopLock to just use started
* Make start() and stop() idempotent
* Forgot to update test after last change, test now accounts for idempotency
* Add extra idempotency on stop check
* Add more descriptive docs of behavior
- Renumbered ApproximateHistogramAggregatorFactory from 8 to 12,
8 was taken by CardinalityAggregatorFactory
- Renumbered ApproximateHistogramFoldingAggregatorFactory from 9 to 13,
9 was taken by FilteredAggregatorFactory
* Avoids fetching all segment records into heap by JDBC driver
* Set connection to read-only to help database optimize queries
* Update JDBC drivers (MySQL has fixes for streaming results)
segment creation deterministic.
This means that each segment will contain data from just one Kafka
partition. So, users will probably not want to have a super high number
of Kafka partitions...
Fixes#2703.
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.
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.
Geared towards supporting transactional inserts of new segments. This involves an
interface "DataSourceMetadata" that allows combining of partially specified metadata
(useful for partitioned ingestion).
DataSource metadata is stored in a new "dataSource" table.
* Eliminate exclusion groups from pull-deps
* Only consider dependency nodes in pull-deps if they are not in the following scopes
* provided
* test
* system
* Fix a bunch of `<scope>provided</scope>` missing tags
* Better exclusions for a couple of problematic libs
