Lineage.Debug.ShowPerformanceDebugMessages
| Writes the data lineage performance information to the mm.log file.
If set to true, writes the following information to the log file:
Metadata Manager prefixes the name of the object for which you ran the data lineage analysis to each performance message.
Default is false.
|
Lineage.Flow.DefaultDownstreamGenerationLimit
| Number of generations to display downstream from the source object in a data lineage diagram.
|
Lineage.Flow.DefaultNumberOfGenerationsToContinueLineage
| Number of generations that appear when you use the arrow buttons to navigate the data lineage diagram.
|
Lineage.Flow.DefaultUpstreamGenerationLimit
| Number of generations to display upstream from the source object in a data lineage diagram.
|
Lineage.PreCompute.ElementsInSingleTransaction
| Maximum number of graph elements, including edges and vertices, that the Metadata Manager Service can process in a single transaction during lineage graph creation. When the number of elements reaches this limit, the Metadata Manager Service pages some information to disk instead of storing it in physical memory.
Increase this value to reduce paging for large, complex data lineage diagrams. If you increase this value, verify that the machine that stores the graph database files has enough physical memory to support the increased transaction size.
Default is 50,000.
|
Lineage.PreCompute.FetchBlockSize
| Number of records that the Metadata Manager Service processes in one block when it retrieves data lineage linking information from the Metadata Manager warehouse to populate the graph database.
If you increase this value, you might also need to increase the value of the Lineage.PreCompute.ElementsInSingleTransaction property because each block of records will contain additional graph elements.
Default is 5000.
