# Proposed changes Load the most recently used stats as FE booted. StatsCacheLoader will record the column(tblid-idxid-colname) it loaded to a map. This PR add a shutdown hook to FE so that we could writes the records in map to the metadata. When booting, Stats of columns that recorded previously would be loaded by a single thread. NOTE This PR add new operation type of log, so the metadata is not backforward compatitable, once user or dev run their FE on the code of this version they cannot rollback to previous FE version.
