hycdong opened a new issue #851: URL: https://github.com/apache/incubator-pegasus/issues/851
In current implementation, table online migration is supported by duplication, this issue raise a new plan to implement it through cold backup and bulk load. In RocksDB, bulk load support a parameter called `ingest_behind`. If `ingest_behind=false`, the bulk loaded data is newest data, otherwise, the data is oldest. As a result, we raise backup and bulk load to implement table online migration, the migration step is: 1. client write old table and new table together 2. old table create a backup 3. convert backup into sst files 4. bulk load sst files with `ingest_behind=true` 5. client stop write old table -- This is an automated message from the Apache Git Service.
