Sharepoint_config transaction database getting large

Sharepoint 2013 on-site is what we are running.  I have a transaction log that gets huge on over the weeken.d  Sharepoint_config is the db.   the database is in simple mode so i dont know why it is doing this.  Does anyone know what jobs a normal sharepoint setup would run that would cause this datbase to get so large on the transaction file size?

Does it shrink back down at all, or stay at the large size. Check to make sure that the backups are running correctly and that the transaction is truncated after the back runs successfully.

Good luck...

I will guess that it's the reindex job.
Do you have regular transaction log backups set for the SharePoint database?

Daily, like once by day?
Depending on the number of transactions, I would recommend to run a transaction log every 15 min or at least every hour. This will help to maintain the transaction log file small.

I turned off the indexing jobs and it still grew to a large state.  I am going to monitor.  I had to shrink it again.  I will continue to monitor

I have faced this issue and it is quite common. It all depends on how many transactions.
We cannot have any control to limit the transactions as it will create more connections which in turn locks or hangs the database. So i always use the below solution to reduce the size of file
USE SharePoint_Config
DBCC SHRINKFILE(N’SharePoint_Config’, 1)

Now it depends on intervals to run
