Hi all, We're starting to prototype Cassandra for use in a production system and became concerned about data corruption after reading the excellent article:
http://blog.evanweaver.com/articles/2009/07/06/up-and-running-with-cassandra/ where Evan Weaver writes: "Cassandra is an alpha product and could, theoretically, lose your data. In particular, if you change the schema specified in the storage-conf.xml file, you must follow these instructions carefully, or corruption will occur (this is going to be fixed). Also, the on-disk storage format is subject to change, making upgrading a bit difficult." Is database corruption a well-known or common problem with Cassandra? What sources of information would you recommend to help devise a strategy to minimize corruption risk, and to detect and recover when corruption does occur? Thanks, Hector Urroz
