memtable_total_space_in_mb does not accept the value 0 in Cassandra 1.0
-----------------------------------------------------------------------
Key: CASSANDRA-3246
URL: https://issues.apache.org/jira/browse/CASSANDRA-3246
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 1.0.0
Reporter: Tyler Hobbs
Priority: Minor
This affects 1.0 beta1.
>From the key explanation in cassandra.yaml it looks like it should accept the
>value "0"
# Total memory to use for memtables. Cassandra will flush the largest
# memtable when this much memory is used.
# If omitted, Cassandra will set it to 1/3 of the heap.
# If set to 0, only the old flush thresholds are used.
memtable_total_space_in_mb: 0
However in the code I could see the following:
if (conf.memtable_total_space_in_mb <= 0)
throw new ConfigurationException("memtable_total_space_in_mb must be positive");
logger.info("Global memtable threshold is enabled at {}MB",
conf.memtable_total_space_in_mb);
