Subject Re: looking at making astyanax asynchronous but cassandra-thrift-1.1.1 doesn't look right
Date Wed, 17 Apr 2013 19:41:19 GMT
Here's an example I did in python a long time ago

Call send() then select on the file handle, when it's ready to read call recv(). 

Or just add more threads on your side :)

see a send(Callback cb) that is typicaly of true asynchronous platforms.  Ie. I don't know
when to call recv myself obviously if I am trying to make astyanax truly asynchronous.

asynch api as our threads would not get held up like they do now.  I guess we can try to crank
it up to 100 threads to get it running a bit faster for now :( :(.
