Hi, I am using Data Streamer API to load the data into ignite cache in embedded mode. But i am seeing intermittent issues. Below is the exception. Sometimes job run successfully and sometimes jobs are hung and the log shows too many of the below exceptions.
I tried upgrading form Ignite 2.7 to 2.7.5 version and removed allowOverwrite(true) which was added. I also tried setting autoFlushFrequency(100) to 100 ms. Still i am seeing the issue.
