# Proposed changes
Issue Number: close #xxx
## Problem summary
1. Refactor file cache. Before refactor, the file cache config format is
"[{"path":"/path/to/file_cache","normal":21474836480,"persistent":10737418240,"query_limit":10737418240}]"
and now change to
"[{"path":"/mnt/disk3/selectdb_cloud/file_cache","total_size":21474836480,"query_limit":10737418240}]".
It will be simpler than before.
2. Support more strategy. Support file cache priority. The file cache will
have three queue, name as 'index'/'normal'/'disposable'. We can avoid that the
higher priority data is eliminate by the lower priority data.
