SQL support for union datasources. (#10324)
* SQL support for union datasources.

Exposed via the "UNION ALL" operator. This means that there are now two
different implementations of UNION ALL: one at the top level of a query
that works by concatenating subquery results, and one at the table level
that works by creating a UnionDataSource.

The SQL documentation is updated to discuss these two use cases and how
they behave.

Future work could unify these by building support for a native datasource
that represents the union of multiple subqueries. (Today, UnionDataSource
can only represent the union of tables, not subqueries.)

* Fixes.

* Error message for sanity check.

* Additional test fixes.

* Add some error messages.

Fix handling of 'join' on top of 'union' datasources. (#10318)
* Fix handling of 'join' on top of 'union' datasources.

The problem is that unions are typically rewritten into a series of
individual queries on the underlying tables, but this isn't done when
the union is wrapped in a join.

The main changes are in UnionQueryRunner:

1) Replace an instanceof UnionQueryRunner check with DataSourceAnalysis.
2) Replace a "query.withDataSource" call with a new function, "Queries.withBaseDataSource".

Together, these enable UnionQueryRunner to "see through" a join.

* Tests.

* Adjust heap sizes for integration tests.

* Different approach, more tests.

* Tweak.

* Styling.

Add SQL "OFFSET" clause. (#10279)
* Add SQL "OFFSET" clause.

Under the hood, this uses the new offset features from #10233 (Scan)
and #10235 (GroupBy). Since Timeseries and TopN queries do not currently
have an offset feature, SQL planning will switch from one of those to
Scan or GroupBy if users add an OFFSET.

Includes a refactoring to harmonize offset and limit planning using an
OffsetLimit wrapper class. This is useful because it ensures that the
various places that need to deal with offset and limit collapsing all
behave the same way, using its "andThen" method.

* Fix test and add another test.

Add note about aggregations on floats (#10285)
* Add note about aggreations on floats

Floating point math is known to be unstable. Due to the way aggregators work
across segments it's possible for the same query operating on the same data to
produce slightly different results.

The same problem exists with any aggregators that are not commutative since
the merge order across segments is not guaranteed.

* Also talk about doubles

* Apply suggestions from code review

ROUND and having comparators correctly handle special double values (#10014)
* ROUND and having comparators correctly handle doubles

Double.NaN, Double.POSITIVE_INFINITY and Double.NEGATIVE_INFINITY are not real
numbers. Because of this, they can not be converted to BigDecimal and instead
throw a NumberFormatException.

This change adds support for calculations that produce these numbers either
for use in the `ROUND` function or the HavingSpecMetricComparator by not
attempting to convert the number to a BigDecimal.

The bug in ROUND was first introduced in #7224 where we added the ability to
round to any decimal place. This PR changes the behavior back to using
`Math.round` if we recognize a number that can not be converted to a
BigDecimal.

Refresh query docs. (#9704)
* Refresh query docs.

Larger changes:

- New doc: querying/datasource.md describes the various kinds of
datasources you can use, and has examples for both SQL and native.
- New doc: querying/query-execution.md describes how native queries
are executed at a high level. It doesn't go into the details of specific
query engines or how queries run at a per-segment level. But I think it
would be good to add or link that content here in the future.
- Refreshed doc: querying/sql.md updated to refer to joins, reformatted
a bit, added a new "Query translation" section that explains how
queries are translated from SQL to native, and removed configuration
details (moved to configuration/index.md).
- Refreshed doc: querying/joins.md updated to refer to join datasources.

Smaller changes:

- Add helpful banners to the top of query documentation pages telling
people whether a given page describes SQL, native, or both.
- Add SQL metrics to operations/metrics.md.
- Add some color and cross-links in various places.
- Add native query component docs to the sidebar, and renamed them so
they look nicer.
- Remove Select query from the sidebar.
- Fix Broker SQL configs in configuration/index.md. Remove them from
querying/sql.md.
- Combined querying/searchquery.md and querying/searchqueryspec.md.

SQL support for joins on subqueries. (#9545)
* SQL support for joins on subqueries.

Changes to SQL module:

- DruidJoinRule: Allow joins on subqueries (left/right are no longer
  required to be scans or mappings).
- DruidJoinRel: Add cost estimation code for joins on subqueries.
- DruidSemiJoinRule, DruidSemiJoinRel: Removed, since DruidJoinRule can
  handle this case now.
- DruidRel: Remove Nullable annotation from toDruidQuery, because
  it is no longer needed (it was used by DruidSemiJoinRel).
- Update Rules constants to reflect new rules available in our current
  version of Calcite. Some of these are useful for optimizing joins on
  subqueries.
- Rework cost estimation to be in terms of cost per row, and place all
  relevant constants in CostEstimates.

Other changes:

- RowBasedColumnSelectorFactory: Don't set hasMultipleValues. The lack
  of isComplete is enough to let callers know that columns might have
  multiple values, and explicitly setting it to true causes
  ExpressionSelectors to think it definitely has multiple values, and
  treat the inputs as arrays. This behavior interfered with some of the
  new tests that involved queries on lookups.
- QueryContexts: Add maxSubqueryRows parameter, and use it in druid-sql
  tests.

* Fixes for tests.

* Adjustments.

Add SQL GROUPING SETS support. (#9122)
* Add SQL GROUPING SETS support.

Built on top of the subtotalsSpec feature in the groupBy query. This also involves
two changes to subtotalsSpec:

- Alter behavior so limitSpec is applied after subtotalsSpec, rather than applied to
  each grouping set. This is more in line with SQL standard behavior. I think it is okay
  to make this change, since the old behavior was not documented, so users should
  hopefully not be depending on it.
- Fix a bug where virtual columns were included in the subtotal queries, but they
  should not have been.

Also fixes two bugs in query equality checking:

- BaseQuery: Use getDuration() instead of "duration" in equals and hashCode, since the
  latter is lazily initialized and might be null in one query but not the other.
- GroupByQuery: Include subtotalsSpec in equals and hashCode.

Add config option for namespacePrefix (#9372)
* Add config option for namespacePrefix

opentsdb emitter sends metric names to opentsdb verbatim as what druid
names them, for example "query.count", this doesn't fit well with a
central opentsdb server which might have namespaced metrics, for example
"druid.query.count". This adds support for adding an optional prefix.

The prefix also gets a trailing dot (.), after it, so the metric name
becomes <namespacePrefix>.<metricname>

configureable as "druid.emitter.opentsdb.namespacePrefix", as
documented.

* Spelling for PR #9372

Added "namespacePrefix" to .spelling exceptions, it's a variable name
used in documentation for opentsdb-emitter.

* fixing tests for PR #9372

changed naming of variables to be more descriptive
added test of prefix being an empty string: "".
added a conditional to buildNamespacePrefix to check for empty string
being fed if EventConverter called without OpentsdbEmitterConfig
instance.

* fixing checkstyle errors for PR #9372

used == to compare literal string, should be equals()

* cleaned up and updated PR #9372

Created a buildMetric function as suggested by clintropolis, and
removed redundant tests for empty strings as they're only used when
calling EventConverter directly without going through
OpentsdbEmitterConfig.

* consistent naming of tests PR #9372

Changed names of tests in files to match better with what it was
actually testing

changed check for Strings.isNullOrEmpty to just check for `null`, as
empty string valued `namespacePrefix` is handled in
OpentsdbEmitterConfig.

Suneet Saldanha 85a3d416b0 Tutorials use new ingestion spec where possible (#9155)
* Tutorials use new ingestion spec where possible

There are 2 main changes
  * Use task type index_parallel instead of index
  * Remove the use of parser + firehose in favor of inputFormat + inputSource

index_parallel is the preferred method starting in 0.17. Setting the job to
index_parallel with the default maxNumConcurrentSubTasks(1) is the equivalent
of an index task

Instead of using a parserSpec, dimensionSpec and timestampSpec have been
promoted to the dataSchema. The format is described in the ioConfig as the
inputFormat.

There are a few cases where the new format is not supported
 * Hadoop must use firehoses instead of the inputSource and inputFormat
 * There is no equivalent of a combining firehose as an inputSource
 * A Combining firehose does not support index_parallel

2019-12-10 14:02:34 -08:00
Chi Cao Minh bab78fc80e Parallel indexing single dim partitions (#8925)
* Parallel indexing single dim partitions

Implements single dimension range partitioning for native parallel batch
indexing as described in #8769. This initial version requires the
druid-datasketches extension to be loaded.

The algorithm has 5 phases that are orchestrated by the supervisor in
`ParallelIndexSupervisorTask#runRangePartitionMultiPhaseParallel()`.
These phases and the main classes involved are described below:

1) In parallel, determine the distribution of dimension values for each
   input source split.

   `PartialDimensionDistributionTask` uses `StringSketch` to generate
   the approximate distribution of dimension values for each input
   source split. If the rows are ungrouped,
   `PartialDimensionDistributionTask.UngroupedRowDimensionValueFilter`
   uses a Bloom filter to skip rows that would be grouped. The final
   distribution is sent back to the supervisor via
   `DimensionDistributionReport`.

2) The range partitions are determined.

   In `ParallelIndexSupervisorTask#determineAllRangePartitions()`, the
   supervisor uses `StringSketchMerger` to merge the individual
   `StringSketch`es created in the preceding phase. The merged sketch is
   then used to create the range partitions.

3) In parallel, generate partial range-partitioned segments.

   `PartialRangeSegmentGenerateTask` uses the range partitions
   determined in the preceding phase and
   `RangePartitionCachingLocalSegmentAllocator` to generate
   `SingleDimensionShardSpec`s.  The partition information is sent back
   to the supervisor via `GeneratedGenericPartitionsReport`.

4) The partial range segments are grouped.

   In `ParallelIndexSupervisorTask#groupGenericPartitionLocationsPerPartition()`,
   the supervisor creates the `PartialGenericSegmentMergeIOConfig`s
   necessary for the next phase.

5) In parallel, merge partial range-partitioned segments.

   `PartialGenericSegmentMergeTask` uses `GenericPartitionLocation` to
   retrieve the partial range-partitioned segments generated earlier and
   then merges and publishes them.

If neither the partition size nor the number of shards are specified,
default to partitions of 5,000,000 rows (similar to the behavior of
dynamic partitions). Previously, both could be null and cause incorrect
behavior.

Specifying both a partition size and a number of shards now results in
an error instead of ignoring the partition size in favor of using the
number of shards. This is a behavior change that makes it more apparent
to the user that only one of the two properties will be honored
(previously, a message was just logged when the specified partition size
was ignored).

* Fix test

* Handle -1 as null

* Add -1 as null tests for single dim partitioning

* Simplify logic to handle -1 as null

* Address review comments

Chi Cao Minh 99b6eedab5 Rename partition spec fields (#8507)
* Rename partition spec fields

Rename partition spec fields to be consistent across the various types
(hashed, single_dim, dynamic). Specifically, use targetNumRowsPerSegment
and maxRowsPerSegment in favor of targetPartitionSize and
maxSegmentSize. Consistent and clearer names are easier for users to
understand and use.

Also fix various IntelliJ inspection warnings and doc spelling mistakes.

* Fix test

* Improve docs

* Add targetRowsPerSegment to HashedPartitionsSpec

Chi Cao Minh 14a8613d69 Exit JVM on curator unhandled errors (#8458)
* Exit JVM on curator unhandled errors

If an unhandled error occurs when curator is talking to ZooKeeper, exit
the JVM in addition to stopping the lifecycle to prevent the process
from being left in a zombie state. With this change,
BoundedExponentialBackoffRetryWithQuit is no longer needed as when
curator exceeds the configured retries, it triggers its unhandled error
listeners. A new "connectionTimeoutMs" CuratorConfig setting is added
mostly to facilitate testing curator unhandled errors, but it may be
useful for users as well.
