JdbcStringBasedStore with MySQL sets up column that uses case-insensitive comparisons for keys ---------------------------------------------------------------------------------------------- Key: ISPN-4984 URL: https://issues.jboss.org/browse/ISPN-4984 Project: Infinispan Issue Type: Enhancement Reporter: Randall Hauch Assignee: Ryan Emerson By default MySQL performs case-insensitive comparisons. This results in a problem when Infinispan entries use Strings that are distinct only in case-sensitive ways, since by default Infinispan's JdbcStringBasedStore (and maybe JdbcBinaryCacheStore) use {{VARCHAR(255)}} for the default {{idColumn}} type. This can of course be corrected in the Infinispan configuration. Rather than specifying this (which is equivalent to the default): {code} <idColumn name="ID_COLUMN" type="VARCHAR(255)"/> {code} the following can be specified instead: {code} <idColumn name="ID_COLUMN" type="VARCHAR(255) CHARACTER SET utf8 COLLATE utf8_unicode_ci"/> {code} This will make MySQL perform case-sensitive comparisons and will work for all string keys. This enhancement request asks that the Infinispan JDBC-based stores use this by default so that it works automatically for MySQL users.
