We > have multiple use cases which does the deletes namely: customer deleting the > data, internal process like GDPR compliance, Phoenix TTL MR jobs. For every > mutations we want to track the source of operation which initiated the > deletes. > At my day job, we have custom Backup/Restore tool. > For example: During GDPR compliance cleanup (lets say at time t0), we > mistakenly deleted some customer data and it were possible that customer also > deleted some data from their side (at time t1). To recover mistakenly deleted > data, we restore from the backup at time (t0 - 1). By doing this, we also > recovered the data that customer intentionally deleted. > We need a way for Restore tool to selectively recover data. > Trying to explain via an example. > Lets say there are 2 different systems (lets say accidental-delete and > customer-delete) deleting the data from the same table at almost the same > time. As the name suggest customer-delete is the intentional delete and > accidental-delete is deletes done by mistake. We have restore tool which will > restore all the data between start time and end times (start-ts and end-ts). > We want to restore the deletes that happened by accidental-delete system and > not want to restore the deletes done by customer-delete system. By adding > cell tag to Delete Markers, we can not restore data done by customer-delete > system. > In my proposal, I want to add cell tags to Tombstone delete marker so that we > have that tag in the backups. Incase we have to restore data, we can restore > specific row depending on the tag present in the cell. > We want to leverage Cell Tag feature for Delete mutations to store these > metadata. Currently Delete object doesn't support Tag feature. > Also we want a solution that can be easily extensible to other mutations like > Put. > Some of the use cases I can think of where we can use tags for Put mutations > are: > 1. Identifying whether the put came from primary cluster or replicated > cluster so that we can make the backup tool more smarter and not backup the > same put twice in source and replicated cluster. > 2. We have a multi-tenancy concept in Phoenix. We want to track whether the > upsert (put operation in hbase) came from Global or Tenant connection. -- This message was sent by Atlassian Jira (v8.3.4#803005)
