----------------------------------------
Summary: Max_SSTable_Age isn't really deprecated in DTCS
Key: CASSANDRA-11350
URL: https://issues.apache.org/jira/browse/CASSANDRA-11350
Project: Cassandra
Issue Type: Bug
Components: Compaction
Environment: PROD
Reporter: Anubhav Kale
Priority: Minor
Based on the comments in https://issues.apache.org/jira/browse/CASSANDRA-10280,
and changes made to DateTieredCompactionStrategyOptions.java, the
Max_SSTable_Age field is marked as deprecated.
However, this is still used to filter the old SS Tables in
DateTieredCompactionStrategy.java. Once those tables are filtered,
Max_Window_Size is used to limit how back in time we can go (essentially how
Max_SSTable_Age was used previously).
So I am somewhat confused on the exact use of these two fields. Should
Max_SSTable_Age be really removed and Max_Window_Size be used to filter old
tables (in which case it should be set to 1 year as well) ?
Currently, Max_SSTable_Age = 1 Year, and Max_Window_Size = 1 Day. What is the
expected behavior with these settings ?
