Hi all, We've downloaded and used Ran's embedded Cassandra helper from the Hector client. It works really well for performing basic integration testing. We have a more advanced test that uses TCP sockets and threading. We send about 400 pieces of data via TCP. This results in ~1200 writes and ~800 reads in our embedded Cassandra over 15 seconds. Occasionally, the test will fail due to less than the 400 packets of data being written, though the calling client code receives no errors from Cassandra on the writes. We see this behavior more on dual processor systems over quad core systems. If we change the tests to use Cassandra running on it's own, the issues seem to disappear regardless of the system size.
This isn't a stress test, just a simple test with a very small input set. Is it possible to tweak any of the storage-conf.xml settings to make the embedded test instance more reliable? We don't need high throughput only reliability to test our code and the results in simple integration tests. Version 0.6.3 Thanks, Todd
