CreateSchema very slow for existing tables RRS feed

  • Question

  • Hi

    We have an existing CE database with about 90 tables in it. We need to call the CreateSchema command (with SyncSchema=null and each SyncTable set to UseExistingTableOrFail), in order to register the table for change tracking.

    I am finding there is a lot of time and CPU spent calling this CreateSchema for all the tables.

    Is this necessary? Is there another function I can call (e.g. I notice the private EnableOcsTracking looks like it could be useful) ?

    Thanks,
    Mark.

  • Well, as a test, I'm calling the EnableOcsTracking via reflection (passing in the Tracking = PK, not ROWGUID), and it's substantially faster.

    I'm just guessing, but it would appear the lookups on the system tables to determine the tracking type are very slow.

  • I am stuck on not being able to find a way to pass in the SETTRACKINGTYPE.PK enum, which is internal, to InvokeMember. It doesn't like a simple numeric value of 1.

     

    Can you share your cool magic?
