Hi Nuwan/Chamara, For the load-balancing/fail-over data publishing, we need to have the following BAM setup.
1) Cassandra servers should be clustered within both BAM nodes. Only then all the data received by the BAM will go to the cassandra cluster, and there won't be any data loss regardless of the receiver is down. 2) Also both analytic scripts in the BAM node should be pointing to the one RDBMS database from which the dashboard is going to render the data. The BAM nodes should be configured as above, then only you can validate the load-balancing/fail-over functionality in proper way. When you have separate Cassandra instance/RDBMS instance, then both BAM summarization will be independent and will consider only the data local to that particular BAM instance. So please setup the BAM as above mentioned, with cassandra cluster and single RDBMS and test the functionality. Thanks, Sinthuja.
