Why use bulk-logged recovery model?
The advantage of using the “Bulk-logged” recovery model is that your transaction logs will not get that large if you are doing large bulk operations and it still allows you to do point in time recovery as long as your last transaction log backup does not include a bulk operation.
What is recovery model bulk logged?
The bulk-logged recovery model is designed for intermittent use to improve the performance of bulk imports of large amounts of data. It’s practically the same as the full recovery model with the only exception that under the bulk-logged recovery model some operations are logged minimally.
What is significance of recovery model setting?
A recovery model is a database property that controls how transactions are logged, whether the transaction log requires (and allows) backing up, and what kinds of restore operations are available.
What are the benefits of using tablock on an insert?
Benefits of using WITH TABLOCK on an INSERT. Under some circumstances, doing an INSERT INTO (WITH TABLOCK) will be faster due to minimal logging. Those circumstances include having the database in the BULK_LOGGED recovery model.
Which is an example of a full recovery model?
Bulk logged. Requires log backups. An adjunct of the full recovery model that permits high-performance bulk copy operations. Reduces log space usage by using minimal logging for most bulk operations. For information about operations that can be minimally logged, see The Transaction Log (SQL Server).
What does efficient logging mean in full recovery?
What you’re seeing in some scenarios in the full recovery model is “efficient logging”, which is the logging of the contents of a page (as opposed to row-by-row logging). It appears that the conditions required for “efficient logging” in full recovery is similar to the conditions required for minimal logging in simple/bulk logged recovery.
When to use tablock hint in SQL Server 2016?
Otherwise, the row is row-compressed. In SQL Server 2016 the TABLOCK hint is required to get parallel insert into heaps, CCIs (Clustered Columnstore Indices), and local temp tables. There are lots of restrictions, some of which aren’t documented. There can’t be an IDENTITY column, the insert can’t be done through an OUTPUT, etc.
