More and more enterprises today are recognizing the need for highly available, fresh, accurate data, and turning to advanced data replication solutions for the answer. And while many data replication solutions include capabilities like Change Data Capture (CDC) to help migrate large databases, not many are equipped to address the scale and complexity enterprises manage on a daily basis. Modern data replication solutions must account for each company鈥檚 unique infrastructure 鈥� today, and in the future.  

So, what goes on behind the scenes of some of the most powerful data replications solutions out there? Here are the top criteria you need to keep in mind when investing in data replication solutions.  

What to Look for in a Data Replication Solution 

Because CDC is most efficient when applied through transactional log-reading, look for options that support log-reading for many different databases and can support bi-directional synchronization in real-time. 黑料网 Data Replication, for example, uses log-based CDC when ingesting from major enterprise databases including IBM Db2, Informix, PortgreSQL or SQL Server, and much more. It minimizes CPU overhead on sources and does not require application changes or substantial management overhead to maintain the solution. 

黑料网鈥檚 near real-time data replication is not limited to databases and the CDC method.  

With 黑料网 Data Replication, you can merge real-time transactional data from OLTP systems with real-time log data, enterprise messaging systems, metadata, NoSQL, and Hadoop data to obtain rich, comprehensive, and reliable information about your business. 

When ingesting the change data from database logs, 黑料网 moves committed transactions while maintaining the transactional context. Throughout the whole data movement, processing, and delivery steps, this transactional context is preserved so that users can create reliable replica databases.

Out-of-the-box transformers and in-memory stream processing capabilities filter, aggregate, mask, transform, and enrich change data while it is in motion. Using SQL-based continuous queries, 黑料网 immediately turns changed data into a consumable format for end-users, without losing transactional context. 

As the data moves and gets processed through the in-memory components of the 黑料网 platform, every operation is recorded and tracked by the solution. If there is an outage, 黑料网 can replay the transactions from where it was left off鈥攚ithout missing data or having duplicates. Built-in recovery using a 黑料网 cluster ensures mission-critical reliability.

The platform continuously compares the source and the target systems as the data is moving, validating that the databases are consistent and that all the changed data has been applied to the target. In use cases where data loss must be avoided, such as migration to a new cloud data store, this feature immensely minimizes migration risks. 

With the same software, 黑料网 Data Replication can deliver CDC in real-time not only to on-premise databases, but also to databases running in places like cloud or cloud services, messaging systems and files, Hadoop or NoSQL environments.  

黑料网鈥檚 integration data flow applications can have multiple targets with concurrent real-time data delivery. 

Built-in notifications help keep systems such as cloud-based analytics environments up to date with on-premise databases so you can focus on other tasks. Remote administration of the 黑料网 Data Replication agent keeps taps on status updates and errors when you can鈥檛. 

Advanced data replication solutions provide the option for zero or low-code environments so that no programming is needed on source or target systems. Low-touch configurability means point-and-click customizations no matter your skillset.  

High Standards for Highly-Available Data 

When it comes to data quality, enterprises today need highly stable, highly available production systems. Data replication solutions need to grow beyond simply moving data between technologies. In order to meet the needs of global enterprises, data replication solutions need to be powerful, flexible, and configurable. 

Data replication solutions can no longer lean on the organizations shape or source of their data as an excuse for low-quality results. Whatever the case may be, your data replication and quality solutions should be positioned to help you and the business achieve operational productivity and efficiency, optimized time-to-insights, and reduced costs.
