This capture only node facilitates import processing for capture at specific time intervals, as specified through a CRON expression. CRON is job scheduler in Unix based operating systems, but it’s expression format is widely accepted as the standard for shorthand notation of a schedule, making it a perfect fit for tasks that require more discrete scheduling than a standard import node provides.
A web search will return numerous quality results to better help you understand CRON expressions. We also recommend this one for building and understanding expressions.
A typical expression will be broken down into 5 positions separated by a space, in the form:
Minute | Hour | Day of Month | Month | Day of Week |
|---|
Example Patterns:
Pattern | Result |
|---|---|
5 4 * * * | Execute at 4:05 AM every day |
1 * 1 1 * | Execute at the 1st minute of the first day of January, annually |
0 9 * * 5 | Execute every Friday at 9AM |
Setup
The CRON Import node supports a few basic options:
Title: All nodes require a Title. This descriptor will display in various views of process history.
Frequency: Frequency indicates how often the workflow engine will evaluate the conditions of this import node. The default frequency for all nodes is 15 minutes. This may be adjusted down to 1 minute, or up to any extended interval you like. In this context, Frequency indicates the interval at which the CRON expression is evaluated. Frequency and the expression can play against each other in cases where your expression identifies an interval that is faster than the specified Frequency.
Source Path: The file pickup location for this import node.
