Data performance tips

Доступно с лицензией Location Referencing.

Proper tuning of the database and the implementation of attribute and spatial indexes during the data loading operation will enhance the performance of any application. This is especially true for ArcGIS Pipeline Referencing because of the extensive data processing steps involved.

To get optimal performance from mapping events in Pipeline Referencing, make sure that your database has the appropriate indexes created. You can use the Add Attribute Index geoprocessing tool to create indexes.

Table nameMulticolumn attribute index fields

LRS Network feature class

  • RouteID
  • From Date
  • To Date
  • Route Name (if configured)
  • Line ID (if configured)
  • Line Name (if configured)

Calibration Point feature class

  • Route ID
  • Network ID
  • From Date
  • To Date

Centerline feature class

  • Centerline ID

For Utility Network:

  • RouteID
  • FromMeasure
  • ToMeasure

Centerline Sequence table

  • Route ID
  • Network ID
  • From Date
  • To Date
  • Centerline ID

Lookup table

  • Key Field
  • (if the lookup table is configured with this field)

Event feature class

  • Event ID
  • Route ID
  • To Route ID (if configured)
  • From Date, To Date

Intersection feature class

  • Route ID
  • From Date
  • To Date

Since the centerline, calibration point, network, and event feature classes are stored in a geodatabase, spatial indexes are automatically created and maintained. In some circumstances, recalculating a spatial index can improve performance.
