# Important: #77411 - Removed extbase table column cache {#important-77411-removed-extbase-table-column-cache}

See [forge#77411](https://forge.typo3.org/issues/77411)

## Description {#description}

The extbase table column cache `extbase_typo3dbbackend_tablecolumns`,
which was used to store all database fields of all database tables,
hass been removed.

The associated configuration variable `$GLOBALS[TYPO3_CONF_VARS][SYS][caching][cacheConfigurations][extbase_typo3dbbackend_tablecolumns]` can safely be removed.
