The main differences are that: the Community Edition is supported by the community, rather than Software AG; The number of threads that the correlator runs on is reduced to four; the number of query definitions is limited to five; and that the Correlator is restricted to using 1GB of memory.

The Apama Core components make up a reduced-footprint version of Apama Community Edition and consist of the Correlator Engine, the client APIs and the command line tools. The Integration Adapter Framework, Eclipse-based IDE, dashboard builder/viewer and third-party database drivers are not included.
The components require less than 100MB of disk space to install and 25MB of memory to run. In addition to supporting Windows and Linux on standard PC hardware, the components are also available for Linux on the Raspberry Pi (model 2 upwards).
