With some effort just before my holiday, I have managed to complete the release of the next version of MyBS, the BLOB streaming engine for MySQL.

This version includes all the basic functionality required to stream BLOB data in and out of MySQL tables.

  • Downloaded of BLOB data directly from the database using HTTP GET.

  • BLOB size may exceed 4GB - theoretical BLOB size limit of 256 Terabytes.

  • BLOBs are stored in a repository which manages references from other storage engine tables.

  • BLOBs are referenced by a URL.

  • URLs referencing BLOBs in the repository have a unique access code, for security.

  • The theoretical maximum repository size is 4 Zettabytes (2^72
