Hi, I have questions regarding the Workflow Manager, particularly the Met File writers and querying data from the File Manager.
1) For files that are required for a PGE task workflow, do I specify the metadata key-value pairs of the file ( e.g Key="TableName" Val="Chartevents" ) in the metout-config.xml ? And, how does the Workflow mgr use the values for the next step/task in the pipeline? 2) To query the File Manager, should I use the Query building option available in the PGETask Workflow Pre-Condition? I have previously used the SQL-like query in a Pge Config file to pull ingested files, but after reading the Workflow 2 Guide, I was wondering if the File Mgr querying should be done in the pre-conditon of a task. So, this would be a pre-condition for checking if input files are available before a task begins. Is this right? Thanks, -Sheryl
