Hector Mutator

[Leandro Rodrigues Silva]

Hello everybody!

I'm using hector for insert columns in runtime on cassandra. But this columns don't appear in metadata, so i need to retrieve that columns. It's possible?

follow my code:

 Keyspace keyspace = HFactory.createKeyspace(getDefaultKeySpace(), cluster);

        Mutator<String> mutator = HFactory.createMutator(keyspace, StringSerializer.get(), new BatchSizeHint(1, keyValuePairs.size()));

        for (Map.Entry<String, Object> entry : keyValuePairs.entrySet()) {

            String property = entry.getKey();

            Object value = entry.getValue();

            HColumn<String, Object> column = createColumn(property, value, StringSerializer.get(), new TypeConverterSerializer<Object>(value));

            mutator.addInsertion(key, colFamily, column);

        }

        mutator.execute();

any ideas??

thanks!!

Leandro, I'm not able to understand you question. Are you trying to store some columns but they are not getting stored after the mutator.execute() returns ?

They are stored, but don't appear on metadata of the column family.

I need in other time, to retrieve the columns that i created in runtime.

for example:

there is a column family like that:

CREATE TABLE users (

user_id text PRIMARY KEY,

first_name text,

last_name text,

emails text

);

but, if my application inserts a new column in runtime, like 'email2'. this one don't appear with user_id, first_name, last_name and emails.

are you understand?

thanks!
