ruby on rails - How to subscribe a Pubnub channel asynchronous? -

-

I want my rail app to subscribe to a global channel, so everything happens on the client, Will be published in I want it to be asynchronous because there will be a lot of messages through that channel, and I want to run it with the rail process. Currently, I can not get it to work, I can call it the initializers / pubnub Rb is inserted: 

  $ pubnub.subscribe (channel: 'global', callback: -> (envelope) {do_something})

I do not get any incoming messages.

Just one usage example in my test app: 

  $ pubnub = Pubnub.new (: subscribe_key = & gt; "demo" ,: publish_key => demo ",: heartbeat => 10,: logger = & gt; Rails.logger) ActiveRecord :: base.establish_connection $ pubnub .subscribe (: channel = & gt;: demo) {| e | Message.create (: content => e.msg)}

This works just fine. Trying to run the code in the callback?

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
