Schema Locks and Time Travel in Fabric Data Warehouse

Louis Davidson continues a comparative analysis:

When reading that title, you probably want to get to concept of time travel first, because if you could really do that, you wouldn’t have any more backup and recovery problems. The time travel I will cover is about getting to past versions of data in your data warehouse tables. This is done in a similar way to what you can do with temporal tables in SQL Server, but also VERY different.

The schema locks section is a wee bit of a follow on to Part 4 where I covered isolation where I showed how updating data was handled concurrently. In this post I wanted to briefly finish that conversation and note how it works when you have schema locks.

Most of this behavior is similar to what we have in SQL Server on-premises, though time travel does have a couple of nuances to it versus the box product.
