High level design overview > * When incremental backup request comes for tables {t} we select all the > tables already registered in a backup system - {T} and union them with {t}, > which results in a new table set - U(t, T) > * For every table K from U(t,T) we perform the following: > ** Convert new WAL files into HFile applying table filter K (only edits for > table T will pass the filter) > ** Move these HFile(s) to backup destination > During restore (incremental): > * We run full restore first > * Then collect all HFiles from intermediate incremental images and run them > through HFileSplitterJob, which splits files into a current tables region > boundaries > * Load these files using LoadIncrementalHFiles tool > -- This message was sent by Atlassian JIRA (v6.3.15#6346)
