    Resolution: Not A Problem

closing as not a problem - better to ask the mailing lists for clarification of these things

> Based on the comments in, and changes
made to, the Max_SSTable_Age field is marked as deprecated.
> However, this is still used to filter the old SS Tables in
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 ?
