Introduction

In NCache 5.0 SP2, there are some important bug fixes and a few new enhancements made.

Enhancements and New Additions

Following are some enhancements made in this release:

1. Support for more than 2 cache clusters in Bridge

   Previously, Bridge could not have more than 2 caches. In this release, NCache now supports to have more than 2 caches in a Bridge. At least one cache must be active.

2. Manual state transfer between Caches in a Bridge

   Even though active caches replicate their data automatically to other caches in a Bridge, the state transfer between the caches is no more active. When a cache goes down or a new cluster is added, a manual interaction to synchronize caches is required.

3. LDAP Security

   LDAP security support is added for both Windows and Linux. Previously, there was no support for LDAP on Linux, while Windows had Active Directory based support.

4. Pub/Sub Enhancements

   Following enhancements have been made in Pub/Sub (TOPIC):

   • Asynchronous message publishing
   • Asynchronous TOPIC creation
   • Bulk message publishing

5. Custom Dependency Enhancements

   Following enhancements have been made to Custom Dependency feature.

   • Bulk evaluation of custom dependencies
   • Multi-threaded evaluation of custom dependencies
   • Extensible notifiable dependencies

6. Configurable Pipelining

   NCache now uses System.IO.Pipelines for high performance IO operations between clients and servers. Due to this approach, NCache is able to perform 2 Million operations per second on a 5 node cluster.

   Pipelining is enabled by default on all caches. However, this can be disabled at the time of cache creation or through modifying cache configuration at any time.

7. Pluggable Modules

   Architectural changes are made to NCache to add support for dynamically registering modules that can use NCache’s distributed architecture without making any changes in NCache source code.

   Lucene.NET support is also added through NCache Modules.

8. More Powershell Cmdlets

   Following Powershell Cmdlets are added:

   • New-Bridge
   • Remove-Bridge
   • Add-BridgeNode
   • Remove-BridgeNode
   • Add-BridgeCache
   • Remove-BridgeCache
