Data Pipeline Optimize Activity

[frithjof_v]

For low code users, it would be awesome if there was a Data Pipeline activity that can be used to run Optimize on a table in a Lakehouse (or all tables in a Lakehouse).

For example, when using Copy Activity or Dataflow Gen2 to append data to a Lakehouse table, the tables need to get optimized (compacted) after x runs. But there is no automated, low-code way to do it. So users forget to optimize the table in the destination Lakehouse.

I agree with this. In addition to optimize, it should also have the option to vacuum. A big selling point of Fabric is that it makes things easy compared to other platforms, so this would be a great step in that direction. SQL Server has had maintenance plans going back at least to SQL Server 2005, I think. So giving Fabric a similar capability to schedule regular maintenance should be a no-brainer.

It could also be beneficial if this mechanism can have AutoCompaction features, so that we can set a threshold to only execute the compaction if the number of small files > x, where x is a threshold value we can adjust, similar to the minNumFiles setting in AutoCompaction https://docs.delta.io/3.1.0/optimizations-oss.html#auto-compaction
