"value" in that message is the name of a column that is expect to be in your table schema - the message is simply complaining that you have no column named "value" in that table. The error concerns the table schema, not any actual data in either the statement or the table.
"metadata" is simply referring to your table schema. Does your table schema have a "value" column? Does your preared statement refer to a "value" column, or are you supplying that name when executing the prepared statement? The "datastax.driver.core" in the exception trace class names indicates that the error is detected in the Java driver, not Cassandra. -- Jack Krupansky On Thu, May 5, 2016 at 6:45 PM, horschi <hors...@gmail.com> wrote: > Hi Jack, > > I thought that it is Cassandra that fills the value on CAS failures.
