The location of the Provenance Repository. The default value is |

The maximum amount of time to keep data provenance information. The default value is |
|
The maximum amount of data provenance information to store at a time. The default value is |
|
The amount of time to wait before rolling over the latest data provenance information so that it is available in the User Interface. The default value is |
|
The amount of information to roll over at a time. The default value is |
|
The number of threads to use for Provenance Repository queries. The default value is |
|
The number of threads to use for indexing Provenance events so that they are searchable. The default value is |

Indicates whether to compress the provenance information when rolling it over. The default value is |
