Changing number of backup from x to y in ignite cluster

I have a ignite cluster running with 8 nodes.

I created one table CREATE TABLE Sample(....) WITH "template=partitioned,backups=1" and it is having 300 Millon entries (cache: "SampleCache")

Now I want to change back up to 0. How can I do this?

Documentation of ALTER doesn't specify anything related to this.

I want to avoid dropping table and creating again.

Solution

  • I'm afraid there's no support for changing cache configuration after it is started. This means you will have to drop table and create another one.
