Hi Jack, I thought that it is Cassandra that fills the value on CAS failures. So the question if it is to be expected to have wasApplied()==false and not have any value in the ResultSet should belong here.
So my question for this mailing list would be: Is it correct behaviour that C* returns wasApplied()==false but not any value? My expectation was that there always is a value in such a case. kind regards, Christian On Wed, May 4, 2016 at 6:00 PM, Jack Krupansky <jack.krupan...@gmail.com> wrote: > Probably better to ask this on the Java driver user list. > > > -- Jack Krupansky > > On Wed, May 4, 2016 at 11:46 AM, horschi <hors...@gmail.com> wrote: > >> Hi, >> >> I am doing some testing on CAS operations and I am frequently having the >> issue that my resultset says wasApplied()==false, but it does not contain >> any value. >> >> >> This behaviour of course leads to the following Exception when I try to >> read it: >> >> Caused by: java.lang.IllegalArgumentException: value is not a column >> defined in this metadata >> at >> com.datastax.driver.core.ColumnDefinitions.getAllIdx(ColumnDefinitions.java:273) >> at >> com.datastax.driver.core.ColumnDefinitions.getFirstIdx(ColumnDefinitions.java:279) >> at >> com.datastax.driver.core.ArrayBackedRow.getIndexOf(ArrayBackedRow.java:68) >> at >> com.datastax.driver.core.AbstractGettableData.getBytes(AbstractGettableData.java:131) >> >> >> >> My questions now are: >> >> Is it to be expected that a failing CAS operation sometimes does this? >> >> if yes: Shouldn't there a possibility on the driver side to handle this >> in a better was, e.g. add a "hasColumn()" method or something to the >> ResultSet? >> >> if no: Is that perhaps a symptom to a greater issue in cassandra? >> >> >> kind regards, >> Christian >> >> PS: I also appreciate general feedback on the entire C* CAS topic :-) >> >> >> >
