About Writers

For each Writer in a process, the following options are available:

• Write Data?

  This option sets whether or not the writer will 'run'; that is, for writers that write to stage data, de-selecting the option will mean that no staged data will be written, and for writers that write to real time consumers, de-selecting the option will mean that no real time response will be written.

  This is useful in two cases:

  1. You want to stream data directly to an export target, rather than stage the written data in the repository, so the writer is used only to select the attributes to write. In this case, you should de-select the Write Data option and add your export task to the job definition after the process.

  2. You want to disable the writer temporarily, for example, if you are switching a process from real time execution to batch execution for testing purposes, you might temporarily disable the writer that issues the real time response.

• Enable Sort/Filter?

  This option sets whether or not to enable sorting and filtering of the data written out by a Staged Data writer. Typically, the staged data written by a writer will only require sorting and filtering to be enabled if it is to be read in by another process where users might want to sort and filter the results, or if you want to be able to sort and filter the results of the writer itself.

  The option has no effect on writers that are connected to real time consumers.
