Tasks

Coyote DX Tasks are simple units of functionality which execute before any DataFrames are read and after all read-write transactions are complete. Their purpose is to initialize and clean up the working environment before and after the transformation process runs. They are designed to operate outside of the read-write cycle.

The original purpose for tasks was to retrieve files from file shares into the working directory to the readers could process those files. The results of processing (what the writers wrote) where then moved to their proper file locations for later retrieval.

Tasks can be created (via Java coding) to perform any function needed, so the toolkit is very open for extension.

If processing is to occur within the read-write cycle, the developer can create a Listener to perform processing when events occur when a data frame is read and written.
