Hi Rishabh, You can read the IdealState by HelixAdmin getResourceIdealState() function and change the number of partitions in the IdealState. Once you are done with it, you can set it back by setResourceIdealState() function in HelixAdmin.
BTW, the number of partition changes does not work for Custom mode and SEMI auto.
