SQL Server Index and Statistics Maintenance performance question
Can somebody share with me his experience in using IndexOptimize for a database with a very high number of indexes ?
You are right, Ola's script first gets data from all the index related DMV's and inserts them inside of @tmpIndexesStatistics, even if one table or one index is specified.
For a lot of indexes, it gets stuck on this first command, which is a fairly huge query. See below for the query and even further below for a possible fix for this.
TL;DR
In one of the queries, the dynamic management views are called a couple of times each with multiple filters.
All this results in a fairly big execution plan.
Creating temp tables and storing the data from the DMV's prior to running the query is a workaround. You could optimize further with indexes on these temp tables / Rewrites.
Test data: >100K empty tables + >200k empty indexes
USE Test2
GO
SET NOCOUNT ON;
DECLARE @SQL NVARCHAR(MAX)
DECLARE @i int = 0
DECLARE @counter int = 1000
WHILE @i <+ @counter
BEGIN
SET @SQL = N'CREATE TABLE dbo.'+QUOTENAME(cast(@i as nvarchar(20)))+'( id int, val varchar(255));'
EXEC(@sql)
SET @SQL = N'CREATE INDEX IX_'+cast(@i as nvarchar(20))+ ' ON '+QUOTENAME(cast(@i as nvarchar(20)))+'(id) '
EXEC(@sql)
SET @SQL = N'CREATE INDEX IX_'+cast(@i as nvarchar(20))+ '_2 ON '+QUOTENAME(cast(@i as nvarchar(20)))+'(val) '
EXEC(@sql)
set @I +=1
IF @i = @counter
BEGIN
IF @counter < 100000
BEGIN
SET @counter += 1000;
END
END
END
select count(*) from sys.tables;
--100731
select count(*) from sys.indexes where index_id != 0;
--201614
When changing the parameters to work on all the indexes, and printing instead of executing the statement ( @Execute='N')
EXECUTE MNGDB.dbo.IndexOptimize
@Databases = 'test2',
@Indexes = 'test2.dbo.',
@FragmentationLow = NULL,
@FragmentationMedium = 'INDEX_REORGANIZE,INDEX_REBUILD_ONLINE,INDEX_REBUILD_OFFLINE',

@FragmentationLevel2 = 50,
@UpdateStatistics = 'ALL',
@OnlyModifiedStatistics = 'Y',
@LogToTable = 'Y',
@LockTimeout = 60,
@Execute='N';
This huge query comes into play

Now, when we try to find what triggers this command inside [dbo].[IndexOptimize]
IF EXISTS(SELECT * FROM @ActionsPreferred) OR @UpdateStatistics IN('ALL','INDEX')
With @ActionsPreferred corresponding to the fragmentationlevel actions and @UpdateStatistics being update statistics. Meaning that it will run whenever we do a stat update or a index rebuild / reorganize.
no filtering is applied, the query runs over all the indexes in the database.
As a result, at the moment we will have to go through all that trouble, even if we specify one table.
EXECUTE MNGDB.dbo.IndexOptimize
@Databases = 'test2',
@Indexes = 'test2.dbo.[83631]',
@FragmentationLow = NULL,
@FragmentationMedium = 'INDEX_REORGANIZE,INDEX_REBUILD_ONLINE,INDEX_REBUILD_OFFLINE',
@FragmentationHigh = 'INDEX_REBUILD_ONLINE,INDEX_REBUILD_OFFLINE',
@FragmentationLevel1 = 30,
@FragmentationLevel2 = 50,
@UpdateStatistics = 'ALL',
@OnlyModifiedStatistics = 'Y',
@LogToTable = 'Y',
@LockTimeout = 60,
@EXECUTE= 'N'
The actual index filtering happen after the the huge command runs:
IF @Indexes IS NULL
BEGIN
UPDATE tmpIndexesStatistics
SET tmpIndexesStatistics.Selected = 1
FROM @tmpIndexesStatistics tmpIndexesStatistics
END
ELSE
BEGIN
...
and updates the tmpIndexesStatistics table accordingly, as to execute index operations on these indexes.
This query was running over 60 minutes on my small dev server before killing it.
What could possibly be a fix for this?
Well, you would have to change ola's script, but a solution with temp tables worked for me, and executed in 1 minute. Without a doubt, it could be optimized further:
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;
USE [test2];
select *
INTO #Indexes
from sys.indexes;
select *
INTO #Index_columns
FROM sys.index_columns;
SELECT *
INTO #columns
FROM SYS.columns;
SELECT *
INTO #types
FROM
sys.types;
SELECT *
INTO #destination_data_spaces
FROM sys.destination_data_spaces;
SELECT *
INTO #filegroups
FROM sys.filegroups;
SELECT *
INTO #stats
FROM sys.stats;
SELECT *
INTO #objects
FROM sys.objects;
SELECT *
INTO #partitions
FROM sys.partitions;
SELECT *
INTO #tables
FROM sys.tables;
SELECT *
INTO #index_resumable_operations
FROM sys.index_resumable_operations
SELECT *
INTO #schemas
FROM sys.schemas
+ rerun the query with temp tables instead (char limit)
To change this in the index optimization procedure
Sorry Ola this will hurt to look at
