TBDEDataSet provides the CacheBlobs property to control whether BLOB fields are cached locally by the BDE when an application reads BLOB records. By default, CacheBlobs is true, meaning that the BDE caches a local copy of BLOB fields. Caching BLOBs improves application performance by enabling the BDE to store local copies of BLOBs instead of fetching them repeatedly from the database server as a user scrolls through records.

In applications and environments where BLOBs are frequently updated or replaced, and a fresh view of BLOB data is more important than application performance, you can set CacheBlobs to false to ensure that your application always sees the latest version of a BLOB field.
