Joel Bernstein updated SOLR-9559:
---------------------------------
Description:
The ExecutorStream will wrap a stream which contains Tuples with Streaming
Expressions to execute. By default the ExecutorStream will look for the
expression in the *expr* field in the Tuples.
The ExecutorStream will have an internal thread pool so expressions can be
executed in parallel in a single worker. The ExecutorStream can also be wrapped
by the parallel function to partition the Streaming Expressions that need to be
executed across a cluster of worker nodes.
Sample syntax:
*code*
executor(topic(storedExpressions, fl="expr", ...))
*code*
was:
The ExecutorStream will execute the stored topics and macros from SOLR-9387.
The ExecutorStream can be pointed at a SolrCloud collection where the topics
are stored and it will execute the topics and macros in batches.
The ExecutorStream will support parallel execution of topics/macros as well.
This will allow the workload to be spread across a cluster of worker nodes.
