period of prolonged and intensive processing this can result in a degradation in performance,
with the whole database slowing down as it struggles to clean itself up.
In Connect terms the effect can be felt as the Data Mapper and/or Job Creation progressively
slowing down.
To cure this issue, it is recommended that you periodically run manual maintenance on the
backend database.
If using MS-SQL, you can run the following command in a query window:
set @a=null,@c=null,@b=concat("show tables where",ifnull(concat("
`Tables_in_",database(),"` like '",@c,"' and"),'')," (@a:=concat_ws
(',',@a,`Tables_in_",database(),"`))");
Prepare `bd` from @b;
EXECUTE `bd`;
DEALLOCATE PREPARE `bd`;
set @a:=concat('optimize table ',@a);
PREPARE `sql` FROM @a;
EXECUTE `sql`;
DEALLOCATE PREPARE `sql`;
set @a=null,@b=null,@c=null;
If using MySQL, the following script should be run in a query window:

Windows 10 Search service impacting Connect
The Windows 10 Search service runs as a background task, indexing files and folders. It has

If this is an issue for you, we suggest disabling Search Indexing on the
C:\Users\<username>\Connect folder.
This issue will be fixed in a later release.
