Rebuild Indexes (Data Management)

Summary

Rebuild existing attribute or spatial indexes in enterprise geodatabases. Indexes can also be rebuilt on states and state_lineage geodatabase system tables and the delta tables of datasets that are registered to participate in traditional versioning. Out-of-date indexes can lead to poor query performance.

Parameters

Dialog

Label	Explanation	Data Type
Input Database Connection	The connection (.sde file) to the database or geodatabase that contains the data for which you want to rebuild indexes.	Workspace
Include System Tables	Indicates whether indexes will be rebuilt on the states and state lineages tables. You must connect as the geodatabase administrator for this option to be activated. This option only applies to geodatabases. If you connect to a database, this option is disabled. Unchecked—Indexes will not be rebuilt on the states and state lineages table. This is the default. Checked—Indexes will be rebuilt on the states and state lineages tables.	Boolean
Datasets to Rebuild Indexes For (Optional)	Names of the datasets that will have their indexes rebuilt. Only datasets that are owned by the connected user are displayed.	String
Rebuild Delta Tables Only (Optional)	Indicates whether indexes will be rebuilt only on the delta tables of the selected datasets. This option will be unavailable if there are no datasets selected in the list of input datasets. This option only applies to geodatabases. If you connect to a database, this option is disabled. Checked—Indexes will only be rebuilt for the delta tables of the selected datasets. This option can be used for cases where the business tables for the selected datasets are not updated often and there are a high volume of edits in the delta tables. This is the default. Unchecked—Indexes will be rebuilt on all indexes for the selected datasets. This includes spatial indexes as well as user-created attribute indexes and any geodatabase-maintained indexes for the dataset.	Boolean

Derived Output

Label	Explanation	Data Type
Updated Workspace	The updated workspace.	Workspace

Python

arcpy.management.RebuildIndexes(input_database, include_system, {in_datasets}, {delta_only})

Name	Explanation	Data Type
input_database	The connection (.sde file) to the database or geodatabase that contains the data for which you want to rebuild indexes.	Workspace
include_system	Indicates whether indexes will be rebuilt on the states and state lineages tables. Note: You must connect as the geodatabase administrator in the connection file you specified for the input_database for this option to be executed successfully. This option only applies to geodatabases. This option is ignored if you connect to a database. NO_SYSTEM— Indexes will not be rebuilt on the states and state lineages table. This is the default. SYSTEM— Indexes will be rebuilt on the states and state lineages tables.	Boolean
in_datasets [in_datasets,...] (Optional)	Names of the datasets that will have their indexes rebuilt. Dataset names use paths relative to the input_database; full paths are not accepted as input.	String
delta_only (Optional)	Indicates how the indexes will be rebuilt on the selected datasets. This option has no effect if in_datasets is empty. This option only applies to geodatabases. If the input workspace is a database, this option will be ignored. ALL—Indexes will be rebuilt on all indexes for the selected datasets. This includes spatial indexes as well as user-created attribute indexes and any geodatabase-maintained indexes for the dataset. ONLY_DELTAS—Indexes will only be rebuilt for the delta tables of the selected datasets. This option can be used for cases where the business tables for the selected datasets are not updated often and there is a high volume of edits in the delta tables. This is the default.	Boolean

Derived Output

Name	Explanation	Data Type
out_workspace	The updated workspace.	Workspace

Code sample

RebuildIndexes example 1 (Python window)

The following example demonstrates how to rebuild indexes using the Python window.

# Import system modules
import arcpy

arcpy.RebuildIndexes_management("c:/Connections/GDB@[e-mail]", "NO_SYSTEM","db1.GDB.Roads;db1.GDB.Parcels", "ALL")

RebuildIndexes example 2 (stand-alone script)

The following example demonstrates how to rebuild indexes in a stand-alone script.

# Name: RebuildIndexes.py
# Description: rebuilds indexes on delta tables for all datasets in an
# enterprise geodatabase

# Import system modules
import arcpy, os

# set workspace
workspace = arcpy.GetParameterAsText(0)

# set the workspace environment
arcpy.env.workspace = workspace

# NOTE: Rebuild indexes can accept a Python list of datasets.

# Get a list of all the datasets the user has access to.
# First, get all the stand alone tables, feature classes and rasters.
dataList = arcpy.ListTables() + arcpy.ListFeatureClasses() + arcpy.ListRasters()

# Next, for feature datasets get all of the datasets and featureclasses
# from the list and add them to the master list.
for dataset in arcpy.ListDatasets("", "Feature"):
    arcpy.env.workspace = os.path.join(workspace,dataset)
    dataList += arcpy.ListFeatureClasses() + arcpy.ListDatasets()

# reset the workspace
arcpy.env.workspace = workspace

# Get the user name for the workspace
userName = arcpy.Describe(workspace).connectionProperties.user.lower()

# remove any datasets that are not owned by the connected user.
userDataList = [ds for ds in dataList if ds.lower().find(".%s." % userName) > -1]

# Execute rebuild indexes
# Note: to use the "SYSTEM" option the workspace user must be an administrator.
arcpy.RebuildIndexes_management(workspace, "NO_SYSTEM", userDataList, "ALL")
print('Rebuild Complete')
