During reprocessing, the data workbench server reconstructs your dataset as you have specified in the Log Processing and Transformation Dataset Configuration files.
To do so, the data workbench server (InsightServer64.exe) must complete both the log processing phase and the transformation phase of dataset construction. When log processing finishes, it triggers transformation to occur automatically, but transformation also can occur independently of log processing.
During the log processing phase, data workbench users do not have access to the data in the dataset. During the transformation phase, data workbench users do have access to up-to-date data, but the data is sampled instead of complete. Data analysis can continue during transformation, but queries will complete only as quickly as the transformation is occurring.
Each time you complete one of the following tasks, log processing, and therefore transformation, occurs automatically to reconstruct your dataset as you have specified in the dataset configuration files:
Add a new data source.
Add a new data workbench server to your cluster in the Profile.cfg file.
Change the Cluster.cfg file.
Change the Log Processing.cfg file or a Log Processing Dataset Include file, including but not limited to the following:
Upgrade your Insight Server.exe file.
You also can initiate reprocessing at any time by entering any character or combination of characters in the Reprocess parameter of the Log Processing.cfg file and saving the file.
For reprocessing to occur, the Pause parameter in the Log Processing Mode.cfg file must be set to false. This parameter’s default value is false, so changing the parameter may not be required. For more information about Log Processing Mode.cfg, see Additional Configuration Files.
Each time you change any information in the Transformation.cfg file or in a Transformation Dataset Include file, such as change a transformation or define a new dimension, transformation occurs automatically.
Each time you change lookup files that are referenced in the Transformation.cfg file or in a Transformation Dataset Include file (including lookup files for Categorize, FlatFileLookup, and ODBCLookup transformations), you must initiate transformation by entering any character or combination of characters in the Reprocess parameter of the Transformation.cfg file and saving the file.
