Summary: Introduce Determinism (and other) Configuration Options
Key: CASSANDRA-16930
URL: https://issues.apache.org/jira/browse/CASSANDRA-16930
Project: Cassandra
Issue Type: Improvement
Reporter: Benedict Elliott Smith
In order to support CEP-10 we must enable deterministic execution within
Cassandra, support disabling certain optional features that are incompatible
with simulation, and support overriding some existing features.
Some determinism will be enabled by the Simulator itself, but there are aspects
of Cassandra that must be made compliant as well. This includes: compression
system-wide, memtable overhead computation, specifying the number of processors
used for computation/decisions, specifing all cache sizes explicitly, enabling
deterministic table IDs, and supporting deterministic node IDs for TimeUUID
creation.
We also want to be able disable sstable activity tracking, and to be able to
happily ignore problems with native filesystem methods and SIGAR. We also want
to be able to override the migration delay, batch sync interval and system auth
replication factor.
For pluggability we also want to be able to specify a custom FailureDetector.
