How Do I Set the TTL for an HBase Table?

  • Set the time to live (TTL) when creating a table:

    Create the t_task_log table, set the column family to f, and set the TTL to 86400 seconds.

    create 't_task_log',{NAME => 'f', TTL=>'86400'}
  • Set the TTL for an existing table:
    disable "t_task_log" #Disable the table (services must be stopped).
alter "t_task_log",NAME=>'data',TTL=>'86400' # Set the TTL value for the column family data.
enable "t_task_log" #Restore the table.
