Hi Gaurav. Could you please share your environment and some details please? 1. Data piece size (like event or entity size in bytes) 2. What is your write rate (like entities per second) 3. How do you evict (delete) data from the cache 4. How many caches (differ by Ignite cache name) do you have 5. What kind of storage do you have (network, HDD, SSD, etc.) 6. If you can provide a solid reproducer, I'd like to investigate it.
