KB4345402 - FIX: Synchronization of a database takes a long time to finish in SQL Server 2017

Symptoms

Assume that you update your installation of Microsoft SQL Server Analysis Services (SSAS) 2016 to Microsoft SSAS 2017. When you synchronize a database in SSAS 2017, the synchronization takes a long time (about two hours) to finish. The same operation in SSAS 2016 takes only about 10 minutes to finish.

Resolution

This fix is included in the following update for SQL Server:

Cumulative Update 10 for SQL Server 2017

About SQL Server builds

Status
