SymmetricDS

JumpMind is excited to announce the release of 3.8.  This release was primarily focused on performance based changes.  Through the process of profiling the code base and addressing a lot of the pain points in the community, we were able to address some key performance improvements.

SymmetricDS, the open source data replication tool for databases and file systems, has a new release of version 3.8.0! This release includes 12 new features and makes 40 improvements! We focused on performance, network efficiency, and monitoring ... [More] capabilities for this version. Here are some highlights: Multiple threads sync channels in parallel, with additional threads for extract, send, and load. Channels can be throttled to limit their network bandwidth. Caching was added to reduce database queries needed for operation. Optimized data gap detection to improve routing performance. Keepalives are used during push and pull to prevent the connection from timing out. Batches retry from staging instead sending over the network again. Monitoring of system problems with notification via email. There is also new support for VoltDB, file sync on Android, and a command line dbcompare tool to resync tables. As a bonus, we now have native binaries for download that are a C-based, client-only implementation for Windows and Linux that offer a deployment option for embedded systems using SQLite. A larger feature list and more details can be found on the project website: http://www.symmetricds.org/news/symmetricds-3-8-0-released [Less]

    SymmetricDS promises to sync your data, but how do you know it really worked?  How do you really know 2 databases are in sync?  Or, maybe you have well-meaning users that come along after the sync, changing data unexpectedly, and throwing ... [More] production out of whack.     Whatever the case, wouldn’t it be nice to be able to compare any 2 databases, and know exactly what the differences are and be able to prove they are in sync?  That’s where a new, experimental feature of SymmetricDS comes in.  It’s called simply dbcompare.  Dbcompare is slated for SymmetricDS 3.8, but if you watch closely, it’s fully included starting in SymmetricDS 3.7.30.

In addition to replicating data changes from source to target you may also wish to populate a table on the target to monitor all events.  In this blog I will show you how to create a simple load filter that will record all changes captured by SymmetricDS into a simple audit table.
