What's New (Replication)
This release of SQL Server introduces several new features and improvements to replication.
Replication Support for AlwaysOn Availability Groups
Replication supports the following features on Availability groups:
A publication database can be part of an availability group. The publisher instances must share a common distributor. Transaction, merge, and snapshot replication are supported.
In an AlwaysOn Availability Group an AlwaysOn secondary cannot be a publisher. Republishing is not supported when replication is combined with AlwaysOn.
Peer-To-Peer (P2P), bi-directional, reciprocal transactional publications, and Oracle Publishing are not supported.
A database that is enabled for Change Data Capture (CDC) can be part of an availability group.
A database enabled for Change Tracking (CT) can be part of an availability group.
Four new stored procedures provide replication support for AlwaysOn.
For more information about replication with AlwaysOn, see Configure Replication for AlwaysOn Availability Groups (SQL Server), Maintaining an AlwaysOn Publication Database (SQL Server), and Replication, Change Tracking, Change Data Capture, and AlwaysOn Availability Groups (SQL Server).
Replication Extended Events
Replication supports Extended Events, however, this feature is for internal use only at this time. Replication extended events were added to help customer support engineers collect information to troubleshoot replication problems. The information collected is not useful for replication performance tuning or monitoring.
Support for 15,000 Partitions
Replication supports up to 15,000 partitions for tables and indexes.
