Hi, It's important to check the number of tickets by kind: if you have many TGTs, that's not surprising, but you should not have many STs, 0 would be expected.
I once had a customer who had enabled refresh tokens and had polluted its cache with them. So it's important to know what you have in store. Then it's a matter of size: indeed, many things are stored in the tickets and all this information is generally useful, but sometimes, you may remove information you don't need, like not tracking the descendant tickets or only keeping the latest access for the same service. These are configuration options you may disable/enable. Thanks.
