Event Generation

The MapR FS File Metadata executor can generate events that you can use in an event stream. When you enable event generation, the executor generates events each time it changes file metadata, creates an empty file, or removes a file or directory.

MapR FS File Metadata events can be used in any logical way. For example:

With the Email executor to send a custom email after receiving an event.
For an example, see Sending Email During Pipeline Processing.
With a destination to store event information.
For an example, see Preserving an Audit Trail of Events.
