有没有像 HDFS 的 DataBlockScanner for Cassandra 这样的东西，即。一种自动机制来检查不经常读取的损坏数据？
最佳答案
没有。
Cassandra doesn't do that automatically - it can guarantee consistency on read or write via ConsistencyLevel on each query, and it can run active (AntiEntropy) repairs. But active repairs must be scheduled (by human or cron or by third party script like http://cassandra-reaper.io/), and to be pedantic, repair only fixes consistency issue, there's some work to be done to properly address/support fixing corrupted replicas (for example, repair COULD send a bit flip from one node to all of the others)
大数据就像垃圾桶。酷。
