* Four changes to scalar_in_array as follow-ups to #16306:
1) Align behavior for `null` scalars to the behavior of the native `in` and `inType` filters: return `true` if the array itself contains null, else return `null`.
2) Rename the class to more closely match the function name.
3) Add a specialization for constant arrays, where we build a `HashSet`.
4) Use `castForEqualityComparison` to properly handle cross-type comparisons.
Additional tests verify comparisons between LONG and DOUBLE are now
handled properly.
* Fix spelling.
* Adjustments from review.
JSON parsing has this function "charsetFix" that fixes up strings
so they can round-trip through UTF-8 encoding without loss of
fidelity. It was originally introduced to fix a bug where strings
could be sorted, encoded, then decoded, and the resulting decoded
strings could end up no longer in sorted order (due to character
swaps during the encode operation).
The code has been in place for some time, and only applies to JSON.
I am not sure if it needs to apply to other formats; it's certainly
more difficult to get broken strings from other formats. It's easy
in JSON because you can write a JSON string like "foo\uD900".
At any rate, this patch does not revisit whether charsetFix should
be applied to all formats. It merely optimizes it for the JSON case.
The function works by using CharsetEncoder.canEncode, which is
a relatively slow method (just as expensive as actually encoding).
This patch adds a short-circuit to skip canEncode if all chars in
a string are in the basic multilingual plane (i.e. if no chars are
surrogates).
Changes:
1) Check for handoff of upgraded realtime segments.
2) Drop sink only when all associated realtime segments have been abandoned.
3) Delete pending segments upon commit to prevent unnecessary upgrades and
partition space exhaustion when a concurrent replace happens. This also prevents
potential data duplication.
4) Register pending segment upgrade only on those tasks to which the segment is associated.
I'm adding OIDC context to the AuthenticationResult returned by pac4j extension. I wanted to use this context as input in OpenPolicyAgent authorization. Since AuthenticationResult already accepts context as a parameter it felt okay to pass the profile attributes there.
Fixes a bug introduced in #16296, where the sketch might not be
initialized if get() is called without calling aggregate(). Also adds
a test for this case.
Issue: #14989
The initial step in optimizing segment metadata was to centralize the construction of datasource schema in the Coordinator (#14985). Thereafter, we addressed the problem of publishing schema for realtime segments (#15475). Subsequently, our goal is to eliminate the requirement for regularly executing queries to obtain segment schema information.
This is the final change which involves publishing segment schema for finalized segments from task and periodically polling them in the Coordinator.
Buffer aggregators can contain some cached objects within them, such as
Memory references or HLL Unions. Prior to this patch, various Grouper
implementations were not releasing this state when resetting their own
internal state, which could lead to excessive memory use.
This patch renames AggregatorAdapater#close to "reset", and updates
Grouper implementations to call this reset method whenever they reset
their internal state.
The base method on BufferAggregator and VectorAggregator remains named
"close", for compatibility with existing extensions, but the contract
is adjusted to say that the aggregator may be reused after the method
is called. All existing implementations in core already adhere to this
new contract, except for the ArrayOfDoubles build flavors, which are
updated in this patch to adhere.
Additionally, this patch harmonizes buffer sketch helpers to call their
clear method "clear" rather than a mix of "clear" and "close". (Others
were already using "clear".)
Changes:
- Use non-static fields to track task counts in `ForkingTaskRunner`
- Update assertions in `ForkingTaskRunnerTest` to ensure that the tests are idempotent
Tries to address the comments made on #16284 after merged.
Changes:
- Remove method `Supervisor.getLagMetric()`
- Add method `Supervisor.computeLagForAutoScaler()`
- Remove classes `LagMetric` and `LagMetricTest`
Statsd client sometimes drops metrics when this queueSize of statsd client with max unprocessed messages is completely full. This causes some high cardinality metrics like per partition lag being droppped.
There are multiple parameters of statsdclient that can be initialized and can help increase the load/capacity of client to not to drop metrics more frequently.
Properties like queueSize, poolSize, processorWorkers and senderWorkers will now be configurable at runtime
* Additional short circuiting knowledge in filter bundles.
Three updates:
1) The parameter "selectionRowCount" on "makeFilterBundle" is renamed
"applyRowCount", and redefined as an upper bound on rows remaining
after short-circuiting (rather than number of rows selected so far).
This definition works better for OR filters, which pass through the
FALSE set rather than the TRUE set to the next subfilter.
2) AndFilter uses min(applyRowCount, indexIntersectionSize) rather
than using selectionRowCount for the first subfilter and indexIntersectionSize
for each filter thereafter. This improves accuracy when the incoming
applyRowCount is smaller than the row count from the first few indexes.
3) OrFilter uses min(applyRowCount, totalRowCount - indexUnionSize) rather
than applyRowCount for subfilters. This allows an OR filter to pass
information about short-circuiting to its subfilters.
To help write tests for this, the patch also moves the sampled
wikiticker data file from sql to processing.
* Forbidden APIs.
* Forbidden APIs.
* Better comments.
* Fix inspection.
* Adjustments to tests.
Changes:
- Add column `task_allocator_id` to `pendingSegments` metadata table.
- Add column `upgraded_from_segment_id` to `pendingSegments` metadata table.
- Add interface `PendingSegmentAllocatingTask` and implement it by all tasks which
can allocate pending segments.
- Use `taskAllocatorId` to identify the task (and its sub-tasks or replicas) to which
a pending segment has been allocated.
- Perform active cleanup of pending segments in `TaskLockbox` once there are no
active tasks for the corresponding task allocator id.
- When committing APPEND segments, also commit all upgraded pending segments
corresponding to that task allocator id.
- When committing REPLACE segments, upgrade all overlapping pending segments in
the same transaction.
Bug:
#15724 introduced a bug where a rolling upgrade would cause all task locations
returned by the Overlord on an older version to be unknown.
Fix:
If the new API fails, fall back to single task status API which always returns a valid task location.
