NCache now provides support for object queries through an object query language (OQL). Download a 60-day FREE Trial from
A distributed cache is typically seen as a hashtable by your application. However, there are times when you want to find objects in the cache based on object attributes rather than a key. Object query language provides you an SQL-like syntax to specify your search criteria. The query then returns a collection of objects from all over the cluster.
NCache also provides a graphical tool for configuring and monitoring clustered caches from a single computer. Performance monitoring is also built into this tool that let's customers immediately see how their application is performing and how each server in the server-farm is contributing toward this performance.
NCache also provides a rich set of clustering topologies to let customers meet their specific needs. This includes Replicated Cache, Partitioned Cache, and Client Cache topologies. Replicated Cache is intended for the most read-intensive applications and keeps copy of the entire cache on each node on the cluster. On the other hand, Partitioned Cache divides up the cache into n equal sized partitions and keeps each partition on each node in the cluster. Partitioned Cache is a little slower than Replicated Cache for small clusters but performs much faster for larger clusters and where reads are not as many as replicated configurations. Finally, Client Cache is intended to allow some of the nodes in the cluster to be either data-less of keep a very small cache on top of the cache.
NCache ensures that all the data in the cache is synchronized always throughout the cluster.
