jackylk opened a new pull request #3459: [CARBONDATA-3582] support table status file backup URL: https://github.com/apache/carbondata/pull/3459 When overwriting table status file, if process crashed, table status file will be in corrupted state. This can happen in an unstable environment, like in the cloud. To prevent the table corruption, user can enable a newly added CarbonProperty to enable backup of the table status before overwriting it. New CarbonProperty: ENABLE_TABLE_STATUS_BACKUP (default is false) When enabling this property, "tablestatus.backup" file will be created in the same folder of "tablestatus" file TODO: add document - [X] Any interfaces changed?
