Extraction properties

The Transaction Server can be used to extract data according to user-defined configurations. These properties apply to Duplicate Detect only. For any other data extracts, use a Services Framework task.
Table 1. Extraction properties
Property Default Value Range Description
maxExtractionWorkers 4 1 - 50 Controls the maximum number of extractions that can run concurrently.
markingWorkerIdleTimeout 300000 10000 - 3600000 The amount of time, in milliseconds, an extraction marking worker thread waits for work to arrive before it terminates. Marking working threads are created, if necessary, when work arrives for processing.

The default timeout is five minutes.
markingWorkerMinimumWait 10000 0 - 60000 The amount of time, in milliseconds, a marking worker waits between marking attempts. If a new marking request arrives before markingWorkerMinimumWait milliseconds has passed since the previous marking attempt, the new request is queued for the next marking attempt. Use this parameter to do the following things.
  • Ensure that there is time for enough work to load to satisfy any aggregation requirements in the extraction profile.
  • Limit the number of attempts that produce empty marks, which reduces unnecessary database activity.

The default for this parameter is ten seconds. To disable waiting between marking attempts, set this value to zero.
