---------------------------------------------
Summary: Guardrail for the number of tables is not working
Key: CASSANDRA-19047
URL: https://issues.apache.org/jira/browse/CASSANDRA-19047
Project: Cassandra
Issue Type: Bug
Components: Cluster/Schema
Reporter: Mohammad Aburadeh
Hi,
We installed Cassandra 4.1.3 and we got the following warning when creating
more than 150 tables:
{code:java}
WARN [Native-Transport-Requests-6] 2023-11-21 18:35:24,585
CreateTableStatement.java:421 - Cluster already contains 161 tables in 6
keyspaces. Having a large number of tables will significantly slow down schema
dependent cluster operations. {code}
I tried to disable "table_count_warn_threshold" by setting its value to "-1"
but that did not work.
Then I tried to set the guardrail for number of tables to "-1" to disable the
above but did not work as well. It seems there is no way to disable checking
the number of tables.
Also, I tried to set "tables_warn_threshold" to a value less than
"tables_count_warn_threshold", it seems Cassandra always uses
"tables_count_warn_threshold" when throwing the warning.
*Two issues in Cassandra 4.1.3:*
1- There should be a way to disable this feature. Either by setting the
guardrail parameter to -1 or setting tables_count_warn_threshold to -1.
2- The guardrail for number of tables should overwrite
tables_count_warn_threshold because I always get the following warning when I
try to increase the number of tables:
{code:java}
WARN [main] 2023-11-21 18:26:16,988 YamlConfigurationLoader.java:427 -
[keyspace_count_warn_threshold, table_count_warn_threshold] parameters have
been deprecated. They have new names and/or value format; For more information,
please refer to NEWS.txt {code}
