The behavior is now that filters on "null" will match rows with no
values. The behavior in the past was inconsistent; sometimes these
filters would match and sometimes they wouldn't.
Adds tests for this behavior to SelectorFilterTest and
BoundFilterTest, for query-level filters and filtered aggregates.
Fixes#2750.
Avoids the following message from being printed on Overlord startup:
WARNING: Parameter 1 of type io.druid.indexing.common.actions.TaskActionHolder<T> from
public <T> javax.ws.rs.core.Response io.druid.indexing.overlord.http.OverlordResource.doAction
(io.druid.indexing.common.actions.TaskActionHolder<T>) is not resolvable to a concrete type
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).
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.
BoundFilter:
- For lexicographic bounds, use bitmapIndex.getIndex to find the start and end points,
then union all bitmaps between those points.
- For alphanumeric bounds, iterate through dimValues, and union all bitmaps for values
matching the predicate.
- Change behavior for nulls: it used to be that the BoundFilter would never match nulls,
now it matches nulls if "" is allowed by the lower limit and not excluded by the
upper limit.
Interface changes:
- BitmapIndex: add `int getIndex(value)` to make it possible to get the index for a
value without retrieving the bitmap.
- BitmapIndex: remove `ImmutableBitmap getBitmap(value)`, change callers to `getBitmap(getIndex(value))`.
- BitmapIndexSelector: allow retrieving the underlying BitmapIndex through getBitmapIndex.
- Clarified contract of indexOf in Indexed, GenericIndexed.
Also added tests for SelectorFilter, NotFilter, and BoundFilter.
Fixes#2682
IndexingService helpers are added according to the settings in runtime.properties.
Rather than having all the config.isXXX checks there, it makes sense to have a pluggable
approach for allowing the dynamic configuration to bring in implementations for helpers
without having to have hard-coded sets of available helpers. Plus, it will also make it possible for extensions to plug helpers in.
With https://github.com/druid-io/druid-api/pull/76, we could conditionally bind a helper to Coordinator's runlist.
The condition is driven by the value set in the runtime.properties.
