Hi All,
Had problems with prepared statements not working with Datastax driver and JDBC
driver. I discovered that when changing indexes yoy need to change column
family caching from All to None then back again. Problem is sometimes CLI
crashes when you do that and you need to run it again. I think I also had to
restart Cassandra also. There was someone saying they were having intermittant
problems with queries and Cassandra and now I think I know why. Also, when
changing from IntegerType to Int32Type ran into indexoutofbounds issue when
getting rows from resultset. Once I changed back to IntegerType I was fine. I
suspect when I loaded up data as IntegerType it caused the problem with
retrieving the rows.
Took me a couple of evenings to get this figured out but now I have to deside
about my data model before I start converting databases to Cassandra. I have
around seven to do and will check statibility for each one at a time by runnng
one several weeks before converting another.
Regards,
Tony
