Hi Ilya,
We have configured atomictyMode 'ATOMIC' for all caches it's not
transactional, below is our cache configuration for one of the caches.
############### Cache Configuration ################
<property name="name" value="DeviceDetailsCache" />
<property name="cacheMode" value="PARTITIONED" />
<property name="atomicityMode" value="ATOMIC" />
<property name="backups" value="1" />
<property name="statisticsEnabled" value="true"/>
I have searched with word 'tcp-comm-worker' in whole log file, could see
single thread tcp-comm-worker-#1
And also attached whole log file, please check ignite.log
<http://apache-ignite-users.70518.x6.nabble.com/file/t2396/ignite.log>
You can refer logs from 2020-12-11 12:50:00 to 12:54:00, we can see the
tread blocked while multiple clients trying to connect to cluster.
