Recently we've been talking about using SegmentIds as map keys rather than
DataSegments, because its sense of equality is more well-defined. This is
a refactor that does this in the druid-sql module, which mostly involves
DruidSchema and some related classes. It should have no user-visible effects.
* SQL: Allow select-sort-project query shapes.
Fixes#7768.
Design changes:
- In PartialDruidQuery, allow projection after select + sort by removing
the SELECT_SORT query stage and instead allowing the SORT and
SORT_PROJECT stages to apply either after aggregation or after a plain
non-aggregating select. This is different from prior behavior, where
SORT and SORT_PROJECT were only considered valid after aggregation
stages. This logic change is in the "canAccept" method.
- In DruidQuery, represent either kind of sorting with a single "Sorting"
class (instead of DefaultLimitSpec). The Sorting class is still
convertible into a DefaultLimitSpec, but is also convertible into the
sorting parameters accepted by a Scan query.
- In DruidQuery, represent post-select and post-sorting projections with
a single "Projection" class. This obsoletes the SortProject and
SelectProjection classes, and simplifies the DruidQuery by allowing us
to move virtual-column and post-aggregator-creation logic into the
new Projection class.
- Split "DruidQuerySignature" into RowSignature and VirtualColumnRegistry.
This effectively means that instead of having mutable and immutable
versions of DruidQuerySignature, we instead of RowSignature (always
immutable) and VirtualColumnRegistry (always mutable, but sometimes
null). This change wasn't required, but IMO it this makes the logic
involving them easier to follow, and makes it more clear when the
virtual column registry is active and when it's not.
Other changes:
- ConvertBoundsToSelectors now just accepts a RowSignature, but we
use the VirtualColumnRegistry.getFullRowSignature() method to get
a signature that includes all columns, and therefore allows us to
simplify the logic (no need to special-case virtual columns).
- Add `__time` to the Scan column list if the query is ordering by time.
* Remove unused import.
* adding a server view that can see all servers
* fixing action-cell snapshot test
* dynamic resize on sql view
* remove extra word
* update home view server tile also
* offer more context options
* pass context to explain also
This change only enables compilation to ensure code compiles against
recent Java versions going forward. Tests are still disabled in this
profile until test failures are addressed.
ambari depends on hadoop-annotation. Under linux, it sometimes activates a
maven profile that includes an explicit dependency on ${java.home}/../lib/tools.jar
This change excludes this dependency, since this jar is no longer
included with Java 9. It also seems seems unlikely that we would require
this dependency at runtime, since it is only enabled on some platforms.
* AggregatorUtil should cache parsed expression to avoid memory problem (OOM/FGC) when Expression is used in metricsSpec
* remove debug log check in Parser.parse
* remove cache and use suppliers.memorize
* add tail dialog checkbox to tasks show-log-component for webconsole
* add check box button css
* add 2 second delay
* left align
* change tail formatting
* use async/await syntax
* add space
* add public prefix
* update jest to reflect changes in show-log
* use sentence case
* update snapshots
This includes the router, overlord, middleManager, and coordinator.
Does the following things:
- Loads LookupSerdeModule on MM, overlord, and coordinator.
- Adds LookupExprMacro to LookupSerdeModule, which allows these node
types to understand that the 'lookup' function exists.
- Adds a test to make sure that LookupSerdeModule works for virtual
columns, filters, transforms, and dimension specs.
This is implementing the technique discussed on these two issues:
- https://github.com/apache/incubator-druid/issues/7724#issuecomment-494723333
- https://github.com/apache/incubator-druid/pull/7082#discussion_r264888771
* Add checkstyle for "Local variable names shouldn't start with capital"
* Adjust some local variables to constants
* Replace StringUtils.LINE_SEPARATOR with System.lineSeparator()
The main motivation is that this fixes#7724, by making it so the overlord
doesn't try to create a task runner and parser when all it really wants to
do is create a task object and serialize it.
