I'm using cassandra 2.1.7 and datastax java drive 2.1.6 Here is the problem:
I use PrepareStatement for query like : SELECT * FROM somespace.sometable where id = ? And I Cached the PrepareStatement in my jvm; When the table metadata has changed like a column was added; And I use the cached PrepareStament , the data and the metadata(column definations) don't match. So I re-prepare the sql using session.prepare(sql) again, but i see the code in the async-prepare callback part: stmt = cluster.manager.addPrepare(stmt); in the SessionManager.java this will return the previous PrepareStatement. So it neither re-prepare automatically nor allow user to re-prepare! Is this a bug or I use it like a fool? -- ------ Joseph Gao PhoneNum:15210513582 QQ: 409343351
