ABFS Vectored Read Is GA: Fewer Round Trips for Selective Reads on Data Lake Storage

If your analytics jobs read small slices of large files in Azure Data Lake Storage, request overhead is probably a bigger cost than raw bandwidth. ABFS Vectored Read is now generally available and targets exactly that pattern.

The idea is simple: compatible analytics engines combine nearby file ranges into fewer storage requests and run the reads asynchronously. The result is fewer network round trips for selective reads, which is where columnar and filtered workloads spend a lot of their time.
