Hello
Is there a requirement for all DMA, Cassandra and search databases to have the same timezone? If nodes are in different time zones, do you expect the DMA to not communicate with databases? Or could it result in incorrect data on the storage?
Thanks.
Hi Srikanth,
I would be very surprised if all the servers in the global Dataminer system (DMAs and DBs) would need to have the same timezone.
On the other hand, for obvious reasons, sharing the same system time is a must, or highly recommended, to say the least.
That's why for a DMS, is a requirement to have all the DMA servers in the cluster, synchronized by some accurate timekeeping service such as NTP. Ideally this synchronization should be extended to the DB clusters (Cassandra/Elasticsearch/Opensearch). To to my understanding, this does not mean we need to have all the nodes in the same timezone (regardless they belong or not to the same cluster).
Please have in mind this is just my educated guess, we should wait for a confirmation from someone who really knows how this fits together.
