Description

Currently we require columns to be marked as blobs in order to enable the blob API. This helps us avoid page overhead and makes writing the blobs easier. However, we should still be able to use the blob API (don't read entire blob in memory) even for data types stored as binary. The scheduler can locate the data and then return the description.

Research direction

Start by tracing the blob API and scheduler paths for columns marked as blobs, then compare how regular binary columns are represented. Done means the blob API can locate and return regular binary values without loading the entire blob into memory, while preserving existing blob-column behavior.
