 ## Mutations
 
 `ALTER` queries that are intended to manipulate table data are implemented with a mechanism called “mutations”, most notably [ALTER TABLE … DELETE](/docs/en/sql-reference/statements/alter/delete.md) and [ALTER TABLE … UPDATE](/docs/en/sql-reference/statements/alter/update.md). They are asynchronous background processes similar to merges in [MergeTree](/docs/en/engines/table-engines/mergetree-family/index.md) tables that to produce new “mutated” versions of parts.
