What is real time replication?
Real time replication is the instantaneous copying of data to one or more places as it is being generated.
In practice, there is always some amount of time that elapses between the moment data is generated, and the moment it is copied. That time lag, often referred to as data latency, can be measured in sub-seconds, seconds, or even minutes. So technically, real-time replication is a relative term.

Common use cases for real time replication
With a variable array of use cases, real time replication is useful for distributing data to other servers used for reporting or application processing, feeding data warehouses, and synchronizing data with remote offices.
Another common use case is to feed business intelligence applications, enabling analysts and other business users to work with the same, up-to-date information that is housed on the original system without impacting its performance. It can also be used to migrate data to a new data store and keep those two systems in sync until testing and cutover is complete. In some cases, data may be transformed to new formats as part of the replication process.
In addition, real time replication can ensure the resilience of IT systems by transmitting changed data and system information to secondary servers that stand ready to assume the production role or to recover data in the event of a disaster.
High availability and disaster recovery (HA/DR) solutions based on real time replication eliminate downtime and the threat of data loss in the event of hardware failure, site outage, natural disaster or simple human error.
