-----------------------------------
Summary: Improve Load Shedding
Key: CASSANDRA-9469
URL: https://issues.apache.org/jira/browse/CASSANDRA-9469
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Benedict
Fix For: 3.x
As discussed in CASSANDRA-9318, load shedding currently provides very few
guarantees and is not employed at every stage of the pipeline. It is relatively
simple to impose bounds on the number of items in a pipeline stage, along with
the age of the items (as we currently impose). We should also ensure that the
predicates are imposed on addition to a pipeline stage, not removal (as in the
mutation/read stage case), since this does not prevent dangerous build up of
outstanding tasks when outlier (or buggy) tasks arrive together (and block
processing).
