I am testing my Java/Spring micro-service application which is using Couchbase. However, in my test scenario, if 2 threads try to update same my id (device_id in my Java class) (I think threads comes at the same time) my program gives exception which is :
org.springframework.dao.OptimisticLockingFailureException: Upsert document with version value failed: 1545056849924849664; nested exception is com.couchbase.client.java.error.CASMismatchException.
So if there is a logic for generating CAS value, how can I change it myself. I want to change cas value so 2 threads can perform update operation and my program does not give exception ? Any suggestion?
