这样一来，一个节点可以计算一个块的散列值；将较小的签名转移到对等节点，该节点也可以计算散列值，然后对两者进行比较。

In this way, a node computes a hash of a block; transfers the much smaller signature to the peer node, which also calculates the hash; and then compares them.

如果对那些列进行更新，则可能导致一行从一个分区转移到另一个分区，从而降低了性能。

Updates to those columns may cause a row to move from one partition to another, resulting in degraded performance.

但是，如果一个表包含可更新的varchar列，或者该表被压缩，那么有可能行的长度会增长，从而导致某一行被转移到其他页上。

But if a table contains updatable VARCHAR columns, or if the table is compressed, it is possible that the row length could grow, which could cause a row to be moved to another page.
