ClouSE version 1.0b.1.0 released

OblakSoft is pleased to announce the release of ClouSE version 1.0b.1.0. This release addresses reliability and performance issues that were encountered by our early adopters, as well as it provides new functionality to better align with real life usage scenarios.

  • The weblob URLs now support user-defined file names.
  • The weblobs now has to be of the LONGBLOB type.
  • The AUTO_INCREMENT fields have now have semantics that is similar to InnoDB’s “interleaved” lock mode.

Thank you all for your feedback!

  • The weblob URLs now support user-defined file names.

We’ve got a lot of feedback that auto-generated names are not SEO-friendly, so instead of specifying an extension (like jpg, gif, etc.) the user can now specify a file name (like creative-thinking.jpg).

  • The weblobs now has to be of the LONGBLOB type.

The BLOB type only supports up to 64 KB of content. Users who followed the examples in our documentation ran into what looked like data corruption: uploading more than 64 KB with streaming worked well, direct access by URL worked well, but getting the content from the SELECT query resulted in content truncation. To avoid confusion, ClouSE now enforces LONGBLOB type for weblob fields.

  • The AUTO_INCREMENT fields have now have semantics that is similar to InnoDB’s “interleaved” lock mode.

Previously, AUTO_INCREMENT was implemented as a global monotonically increasing counter; the existing values in the table were not taken into account. The old implementation did not work well in cases like restoring tables from a backup taken by mysqldump: the values from the backup could conflict with the new values produced by the ClouSE’s global counter. The new implementation uses existing values to generate new auto-incremented values, such that the new values are higher than any existing value in the table.
