Continuous Querying describes how to implement continuous querying in the Pivotal GemFire native client so that C++ and .NET clients can run queries against events in the GemFire cache server region. It also describes main features and the native client CQ API.
C++ and .NET clients register interest in events using simple query expressions. Events are sent to client listeners that you can program to do whatever your application requires.
Implementing a Continuous Query
You can specify CQs for any client region.
This section discusses how to access and manage your CQs from your client. The calls discussed here are all executed specifically for the calling client. A client cannot access or modify the CQs belonging to another client.
This chapter documents the primary native client API for CQ management.
