current 255 character limit. This is only problem on MySQL, on other<br />
DBs we use TEXT, which has no length limit.</p>
<p>On MySQL, just increasing the column length to 1024 is not enough,<br />
there's a limit on maximum length of VARBINARY/VARCHAR index, which is<br />
756 bytes (255 characters). To be able to have an index on a VARBINARY<br />
column with up to 1024 characters we need to enable innodb_large_prefix<br />
and change how the extra characters are stored on the disk (ROW_FORMAT).</p></div></div><br /><div><strong>TEST PLAN</strong><div><p>Modified a unit-test to attempt creating an Item with 1024 characters long RID</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R165 Akonadi </div></div></div><br /><div><strong>BRANCH</strong><div><div>master</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D21714">https://phabricator.kde.org/D21714</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>autotests/libs/itemappendtest.cpp<br />
