   > @mathieudruart can you send me some doc/examples to produce batch message 
scenarios where the code fails. Need it to fix the test cases.
   
   Hi @KKcorps, here is an example scenario with which we reproduce the problem 
:
   
   - activate infinite [retention 
policy](https://pulsar.apache.org/docs/en/cookbooks-retention-expiry/) on a 
Pulsar namespace (this will make it easier to reproduce the problem) : 
`pulsar-admin namespaces set-retention my-tenant/my-ns --size -1 --time -1`
   - use a Pulsar client to push messages with batch activated into a topic of 
the previous namespace (the Pulsar java client activates batches by default)
   - create a table into Pinot linked to the previous topic (all messages will 
be loaded correctly)
   - send new batch messages into the topic => the first messages will be 
skipped (the number of skipped messages depends on the size of the last 
correctly consumed batch)
   
   Don't hesitate to ask me for clarification.
