This is to help guard against data loss in the case of a hardware failure. To do so, you have to specify the path to your MongoDB installation when starting the mongod instance. Avoid re-using _id values even if no. If a disaster occurs, it is assumed that there will be downtime in order to perform tasks needed to recover the service in the other datacenter. You can use mongodump and mongorestore to seed MongoDB Atlas clusters from an existing standalone, replica set, and sharded cluster. Two data centers are in separate regions (South Central US and East US 2) with approximately ~27ms round-trip latency between them. Cross. To achieve this, a replica set will have a single Primary node (which writes will go to), and Secondaries (which can take over should something happen to the Primary). It’s come a long way from its origins. CH loading nodes (which ingest data) should be as close as possible to ZK (better. . This way, any analytics jobs that are running.
