Default blob size for mysql ddl too small
-----------------------------------------
Key: JCR-760
URL: https://issues.apache.org/jira/browse/JCR-760
Project: Jackrabbit
Issue Type: Improvement
Components: core
Affects Versions: 1.2.2
Reporter: fabrizio giustina
Priority: Minor
the default datatype for:
NODE.NODE_DATA
PROP.PROP_DATA
REFS.REFS_DATA
in the mysql ddl is "BLOB" which is pretty small to the default size in other
dbs.
When playing with a (not very large) jackrabbit repo using mysql for
persistence I easily got data truncation errors on both NODE.NODE_DATA and
PROP.PROP_DATA columns. The same issue has been reported in the past by other
users.
Although anyone could easily create a custom ddl with larger fields it should
be nice to increase the blob size in the mysql ddl embedded in jackrabbit, in
order to avoid this kind of problems for new users (you usually learn this the
hard way, when the number of nodes in your repository starts to grow and
jackrabbit start throwing errors :/).
Changing BLOB to MEDIUMBLOB will make the default size for mysql more similar
to the one in other dbs, without critically increasing the used space...
