+ 6.25 How does BLOB streaming work in phpMyAdmin?

+ +

First, for general information about BLOB streaming on MySQL, visit blobstreaming.org. We currently support streaming if you are running MySQL 5.1 with the PBXT and PBMS storage engines.

+

    +
  1. In config.inc.php your host should be defined with a FQDN (fully qualified domain name) instead of something like "localhost".
    2. +
  2. A current limitation is that your first login via phpMyAdmin to a freshly-started server must be done with an account that has the SUPER privilege.
    3. +
  3. On your target database, go to Operations and in the "BLOB Repository" section, click "Enable". This creates the PBMS system tables inside your database.
    4. +
  4. Ensure that your target table has a LONGBLOB column.
    5. +
  5. When you insert or update a row in this table, put a checkmark on the "Upload to BLOB repository" optional choice; otherwise, the upload will be done directly in your column instead of the repository.
    6. +
  6. Finally when you browse your table, you'll see in your column a link to stream your data, for example "View image". A header containing the correct MIME-type will be sent to your browser; this MIME-type was stored at upload time but in case it's incorrect, it's possible to edit it by clicking on the displayed MIME-type.
