> 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}
