Reza Vaghefi updated CASSANDRA-20647:
-------------------------------------
Description:
The reported values for LiveDiskSpaceUsed and TotalDiskSpaceUsed metrics are
incorrect for tables with SASI Index.
The initial values seem to be correct, however, they get corrupted after each
compaction and eventually drop to below zero (negative value).
Restarting Cassandra resolves the issue.
*Steps taken to reproduce the issue:*
* Created a table with SASIIndex and inserted a few rows:
*
**
{code:java}
CREATE KEYSPACE cycling WITH REPLICATION = { 'class' :
'NetworkTopologyStrategy', 'DC1' : 3 };
CREATE TABLE cycling.cyclist_name ( id UUID PRIMARY KEY, lastname text,
firstname text );
CREATE CUSTOM INDEX fn_contains ON cycling.cyclist_name (firstname) USING
'org.apache.cassandra.index.sasi.SASIIndex' WITH OPTIONS = { 'mode': 'CONTAINS'
};
INSERT INTO cycling.cyclist_name (id, lastname, firstname) VALUES
(6ab09bec-e68e-48d9-a5f8-97e6fa4c9b40, 'Doe','John');
INSERT INTO cycling.cyclist_name (id, lastname, firstname) VALUES
(6ab09bec-e68e-48d9-a5f8-97e6fa4c9b41, 'Doe','John');
INSERT INTO cycling.cyclist_name (id, lastname, firstname) VALUES
(6ab09bec-e68e-48d9-a5f8-97e6fa4c9b42, 'Doe','John'); {code}
* nodetool flush
