Silly question
Using the CQL driver for conditional updates, I¹m looking into the ResultSet
that comes back:
for (ColumnDefinitions.Definition definition :
results.getColumnDefinitions().asList()) {
for (Row row : results.all()) {
LOG.debug("UPDATE APPLIED = [{}]=[{}]",
definition.getName(), row.getBool(definition.getName()));
}
}
I noticed that the ResultSet of a conditional update contains a column
³[applied]², with a boolean indicating whether or not the update was
applied.
I assume this column name comes from:
src/java/org/apache/cassandra/cql3/statements/ModificationStatement.java:50
private static final ColumnIdentifier CAS_RESULT_COLUMN = new
ColumnIdentifier("[applied]", false);
Does it make sense to expose this column name as a String constant
somewhere?
Either in the CQL java-driver, or Cassandra itself?
