maxwellguo commented on CASSANDRA-15402:
----------------------------------------
*I just add the feature of incremental backup configurable per keyspace and
table .
First of all , all the table will be added to a map at startup when the
incremental_backup flag is set to true, which means all the table will take off
incremental backup.
Through nodetool of enablebackup /disablebackup we can enable backup and
disable backup for the specified keyspace and table.Also the commadn of
statusbackup will show the status of keyspace/table that turn on incremental
backup.
At first I want to add a configuration to cassandra.yaml to do keyspace/table
's backup filter, but latter i give up for I think the configuration file is of
too much configuration .So I made a default configuration for
all keyspace to turn on backup at setup.

> We know that when we do backup for cassandra, we can do full bakcup with
> snapshot, when we need to backup incremental data , incremental_backup can do
> some help .
> For snapshot we can just make snapshot for some keyspace/table. but
> incremental backup will do all data backup(make hard link for all sstable
> that flush from memtable or streaming ). we also know that commitlog's replay
> can do some keyspace /table 's filter.
> So I think for incremental backup we also need some filter for it.After all
> not all keyspace/table is so important to do backup.
