In the previous post, we showed how we used MongoDB replication to solve several problems we were facing.. Replication got to be a part of a bigger migration which brought stability, fault-tolerance, and performance to our systems. Replication lag is calculated between the last operation time on the primary and the time of the last operation received by the secondary. For simplicity in comparison, let’s focus on replication for high availability and global deployments across multiple DCs. To be replicated, these datasets must meet the following requirements: The database user must have write access to the data. application instances and clients. In simple words, in production environments large data manipulation is going on simultaneously so at that time the application database should be capable enough to handle large queries. information on Global Writes zones, see Global Write Zones and Zone Mapping. As you probably know, Tungsten Replicator can replicate data from MySQL to MongoDB. Feature incompatible with Multi-Cloud Clusters. selected cluster. It is supposed to provoke inspiration and conversation while we work, test and get the bugs out. Replication is automatically integrated when we are using MongoDB Atlas.
