We are using ES 8.2 since one and a half year. Planning to upgrade it to ES2 9.5.
So, I was checking the steps and suddently wondered to see our current GDS size is 100.5 GB!! We have many long lived processes, but the active RUNNING process instances are close to 40000 (40 thousand). Other processes are in completed state. Isn't this size too big from normal?
If so, Can you help me the ways to clean the GDS without disturbing the running instances?
