Using hector (cassandra client) when I try to do delete, it deletes the columns…but leaves the row key behind…does anyone know why, and how can I delete that row key as well ?

推荐答案

这是使用Cassandra时的预期。因为它通过写入墓碑删除，数据仍然存在，直到下一个压缩。最终，它会完全成功，但你的应用程序代码必须知道一个空行与被删除的行相同。

This is expected when using Cassandra. Since it deletes by writing tombstones the data is still there until the next compaction. Eventually it will go a way completely, but your application code must be aware that an empty row is the same as a deleted row.
