Set cell-level TTL for existing rows in HBase

[#1]

Hi Community,

We are working on a new requirement where I need to disable table-level TTL and rather use cell-level TTL for one of our HBase tables.

I can disable the table-level TTL by altering the table property and set cell-level TTL for new incoming data. However, I can't find anything on how can I set cell-level TTL for the data / rows that are already existing in the table.

Any suggestions will be very helpful.

Thank you,

Cell TTL is something that is defined at insertion time. So for an already existing data, you can perform a put of the same cell, which then will have the exact cell value on a new Hfile with the new TTL for the cell.
