Hi all, Greeting for this day. I have successfully inserted data into the riak database using riak-python client and currently, I'm using single node configuration. I'm refering to http://riak-python-client.readthedocs.io/en/2.2.0/client.html this website for a tutorial but I'm having lots of problem in getting the clear solution. my system configuration is: OS - Ubuntu Trusty LTS Python - 2.7.6 Riak KV - 2.1.4 So my question is that now: Q) I want to see what are all the buckets that are present in my database at this moment? http://riak-python-client.readthedocs.io/en/2.2.0/client.html#riak.client.RiakClient.stream_buckets Q) If I know the name of the buckets then is there any way to retrieve all the keys that bucket have? http://riak-python-client.readthedocs.io/en/2.2.0/client.html#riak.client.RiakClient.get_keys http://riak-python-client.readthedocs.io/en/2.2.0/client.html#riak.client.RiakClient.stream_keys Q) Is there any possibility by which we can specify the WHERE condition as we do in SQL? Yes and no. The basic .get will return a contents where bucket= and key= http://riak-python-client.readthedocs.io/en/2.2.0/client.html#riak.client.RiakClient.get Beyond that you would need to setup riak search http://docs.basho.com/riak/kv/2.2.1/developing/usage/search/ or secondary indexes http://docs.basho.com/riak/kv/2.2.1/using/reference/secondary-indexes/ Please help me in this. Any documentation or website or any kind of help is apprecited. Mr. Coder, MTECH in Distributed Database, National Institute of Technology. INDIA
