Juho, do you mind sharing your implementation with the group?

Re: Thrift + PHP: help!
Interesting! Thanks for sharing
Have you considered instead of retrying the failing node, to iterate
through other nodes in your cluster?
If one node is failing (let's assume it's overloaded for a minute),
you're probably going to be better off having the client send the insert
to the next node in line.
Thoughts?

Basically each api call is wrapped inside a retry loop as we can
assume that each operation can be retried as many times as needed:
$tries = 0;
$this-last_exception = null;
$delay = 1000; // start with 1ms retry delay
do {
try {
$this-client-insert($this-keyspace, $key,
$column_path, $value,

return;

Logger::error(InvalidRequestException: .
$e-why . ',
stacktrace: ' . $e-getMessage());
throw $e;
} catch (Exception $e) {
$this-last_exception = $e;
$tries++;
// sleep for some time and try again
usleep($delay);
$delay = $delay * 3;
$this-connect(); // Drop current server and
reopen a connection
into another server
}
} while ($tries 4);
// Give up and throw the last exception
throw $this-last_exception;

Yes, the $this-connect() does just that: it removes the previous node
from the node list and gives the list back to thrift connection
function. In case all nodes have been tried (and thus removed) it
refills the node list and starts looping it again. In practice this
will never happen but the code is there just to be sure :)

Re: Thrift + PHP: help!
I have had to build a wrapper around php thrift calls which automatically retry the cassandra thrift operation in case there was a failure. It's not a proper sollution, but it has worked in our case well enough to be reliable. Of course it would be nice if I wouldn't need such ugly hack. - Garo On Wednesday, August 18, 2010, Jeremy Hanna jeremy.hanna1...@gmail.com wrote: As Jonathan mentioned in his keynote at the Cassandra Summit, the thrift + php has some bugs and is maintainerless right now.

I am a user of the perl api - so I'd like to lurk in case there are things that can benefit both perl php.
