It would be really nice to be on par with hbase async support and have async for cassandra.
any movement on adding async support now that thrift has it? as PlayOrm is based on astyanax and would LOVE to add asynchronous support for calls into cassandra like public void find(keyList, responseCallback) so responses are fired back to the client as they come in not holding up any threads.
NOTE: We have an csv upload of 1 million rows that we use PlayOrm and we have 20 threads writing for the one POST request sent by the client. We noticed on performance 100k rows takes 33 seconds with a synchronous playorm flush and simulating an asynch flush, it only takes 3 seconds to complete(10 times performance boost so we can return to client faster). Will asynch be implemented in astyanax or will a git pull be accepted if we try to do one?
We weren't planning to implement this any time soon. A pull request for this would be greatly appreciated.
shoot, this is looking like it will be a huge challenge since asyanax uses TSocket and not TNonblockingSocket :(
You should be able to write a new ThriftAsyncConnectionFactoryImpl based on ThriftSyncConnectionFactoryImpl. It may also be necessary to further abstract the Client class from ThriftKeyspaceImpl.
thanks for the tip, we will look into that.
Quick question I hope. I checked it out and ran the typical "./gradlew build" which fails. Is the current master branch in a failure state(I want to start from a good working state)....
The error is thus(which is not what I am used to as usually it just says the test that failed in gradle?)
FAILURE: Build failed with an exception.
ah, never mind, can't have cassandra running.
Closing this out assuming that there isn't any outstanding issue here.
