I am using helenus in my node-js project to get/set values in cassandra. I have a MapType field inside my Table, but when I retrieve the value from the table, I get an empty key-value set.
Below is the schema for my table
CREATE TABLE datapoints (
id uuid PRIMARY KEY,
created_at timestamp,
properties map<text,text>
);
I have inserted the values from cql using the query below
INSERT INTO datapoints (id, properties) VALUES (24053e20-63e9-11e3-8d81-0002a5d5c51b, { 'fruit' : 'apple', 'band' : 'Beatles' });
Below is my nodejs code:
var helenus = require('/usr/local/lib/node_modules/helenus')
var pool = new helenus.ConnectionPool({
hosts : ['localhost:9160'],
keyspace : 'mykeyspace',
timeout : 3000
});
pool.connect(function(err, keyspace){
if(err){
console.log("connect me error")
throw(err);
} else {
pool.cql("SELECT * FROM datapoints", [], function(err,results){
console.log("results", results)
results.forEach(function(row){
props = row.get('properties').value;
var id = row.get('id').value;
console.log("properties", props);
console.log("id", id);
});
})
}
});
The line console.log("properties", props); returns me a function, and when I call that function, I get an empty key value set. Please help.
