I am using hector API for cassandra.
i create a counter table like follows
private void addColumnFamilyCounter(ThriftCluster cluster, String cfName, int rowCacheKeysToSave) {
String cassandraKeyspace = this.env.getProperty("cassandra.keyspace");
ThriftCfDef cfd =
new ThriftCfDef(cassandraKeyspace, cfName, ComparatorType.UTF8TYPE);
cfd.setRowCacheKeysToSave(rowCacheKeysToSave);
cfd.setDefaultValidationClass(ComparatorType.COUNTERTYPE.getClassName());
cluster.addColumnFamily(cfd);
}
and call the above method like follows
addColumnFamilyCounter(cluster, COUNTER_CF, 0);
The format of the table is like follows
Primary key columns
Munich jingle : 1
mingle : 2
tingle : 1
pingle : 5
Now i want to execute a query to get all the columns and their values under Munich. is there any way i can get all the columns.
What i knw till now is the following query but it gives me value for only a combination of primary key and a column key.
@Override
public long getTagCounter(String domain, String tag) {
CounterQuery<String, String> counter =
new ThriftCounterColumnQuery<String, String>(keyspaceOperator,
StringSerializer.get(),
StringSerializer.get());
counter.setColumnFamily(TAG_COUNTER_CF).setKey("p_key").setName("name");
return counter.execute().get().getValue();
}
