A correlator deployment package (CDP) is a file that contains application EPL code in a proprietary, non-plain-text format. These files treat EPL files similarly to the way Java files are treated in JAR files. CDP files can be created by Exporting from Apama Studio projects or by using the engine_package utility. CDP files can be injected to the correlator just as EPL files and JAR files containing Apama Java applications are injected.
