* 修改列类型。必须与原始类型兼容，否则复制将失败。例如，可以将`UInt32`列修改为`UInt64`，不能将 `String` 列修改为 `Array(String)`。
* 修改 [column TTL](../table-engines/mergetree-family/mergetree/#mergetree-column-ttl).
* 修改 [column compression codec](../../sql-reference/statements/create/table.md/#codecs).

: ClickHouse keeps data structures in memory that allows reading not only used columns but only necessary row ranges of those columns.
Data compression
: Storing different values of the same column together often leads to better compression ratios (compared to row-oriented systems) because in real data column often has the same or not so many different values for neighboring rows. In addition to general-purpose compression, ClickHouse supports [specialized codecs](../../sql-reference/statements/create/table.md/#create-query-specialized-codecs) that can make data even more compact.
