This commit does two things:
* Allow users to plug-in different implementations of the handler (they must extend HealthCheckHandler)
* Remove the HealthCheckHandler from the implicit SolrCore plugins
This commit introduces CPU based circuit breaker. This circuit breaker
tracks the average CPU load per minute and triggers if the value exceeds
a configurable value.
This commit also adds a specific control flag for Memory Circuit Breaker
to allow enabling/disabling the same.
Prior to this commit, the wrapup logic at the end of
DocBuilder.execute() closed out a series of DIH objects, but did so
in a way that an exception closing any of them resulted in the remainder
staying open. This is especially problematic since Writer.close()
throws exceptions that DIH uses to determine the success/failure of the
run.
In practice this caused network errors sending DIH data to other Solr
nodes to result in leaked JDBC connections.
This commit changes DocBuilder's termination logic to handle exceptions
more gracefully, ensuring that errors closing a DIHWriter (for example)
don't prevent the closure of entity-processor and DataSource objects.
This commit introduces two functionalities: request rate limiting and ability to identify requests based on type (indexing, search, admin). The default rate limiter rate limits query requests based on configurable parameters which can be set in web.xml. Note that this rate limiting works at a JVM level, not a core/collection level.
This issue occurs only while fetching uncommitted doc through /get.
Instead of directly calling stringValue() on IndexableField use
FieldType's toExtern() or toObject() to get the writable value for the field.
* SolrRrdBackendFactory should not be created if history is disabled
* Disable MetricsHistoryHandler by default in tests
* Await shutdown of all executors
This adds a lot of "under the covers" improvements to how JSON Faceting FacetField processors work, to enable
"sweeping" support when the SlotAcc used for sorting support it (currently just "relatedness()")
