I want to check if a column exists in cassandra table in java,and then perform an action if it exists.How do I do that?

Solution

  • You can get table definition via Metadata class. Something like:

    Column column = cluster.getMetadata().getKeyspace("ks-name")
   .getTable("table-name").getColumn("column-name");
if (column != null) {
   // do your stuff
}
