Optimizing with Delta
Delta's support for ACID transactions and quality guarantees helps ensure data reliability, thereby reducing superfluous validation steps and shortening the end-to-end time. This involves less downtime and triage cycles. Delta's support of fine-grained updates, deletes, and merges applies at a file level instead of to the entire partition, leading to less data manipulation and faster operations. This also leads to fewer compute resources, leading to cost savings.
Changing the data layout in storage
Optimizing the layout of the data can help speed up query performance, and there are two ways to do so, namely the following:
- Compaction, also known as bin-packing
- Here, lots of smaller files are combined into fewer large ones.
- Depending on how many files are involved, this can be an expensive operation and it is a good idea to run it either during off-peak hours or on a separate cluster from the main pipeline to avoid unnecessary delays to the...
