Supports binary protocol working group charter mentions several goals and issues of concern: The proposed changes do not require any changes to how existing web applications work, but new applications can take advantage of new features for increased speed. What is new is how the data is framed and transported between the client and the server. Websites that are efficient minimize the number of supports binary protocol required to render an entire page by minifying reducing the amount of code and packing smaller pieces of supports binary protocol into bundles, without reducing its ability to function resources such as images and scripts.

However, minification is not necessarily convenient nor efficient and may still require separate HTTP connections to get the page and the minified resources. This allows the server to supply data it knows a web browser will need to render a web page, without waiting for the browser to examine the supports binary protocol response, and without the overhead of an additional request cycle.

The basic changes made to HTTP 1. SPDY split requests into either control or data, using a "simple to parse binary protocol with two types of frames". This helps to reduce the potential for compression oracle attacks on the protocol, such as the CRIME attack. Most concerns, however, have been related to encryption issues. Initially, some members [ who? Critics stated that encryption has non-negligible computing costs and that many HTTP applications have actually no need for encryption and their providers have no desire to spend additional resources on it.

Encryption proponents have stated that this encryption overhead is negligible in practice. From Wikipedia, the free encyclopedia. Comparison of web server software.

So far, CQL has still been using Thrift as a network transport. This was done initially out of convenience, because we wanted to focus on the language first, and Thrift was there, provided us a transport for free and is relatively fast.

But CQL is in no way tied to Thrift for the transport, and while Thrift has advantages, it also comes with a few limitations:. Also, Thrift is a generic framework, and we believe that a transport specifically tailored for Cassandra might bring additional control and maybe performance.

This has led to the new binary protocol that will be introduced by Cassandra 1. This protocol is a custom one and has been designed specifically for Cassandra and more precisely for CQL3 that is, it only support CQL3. Amongst others, it offers the following features:. Interested parties can find the full specification for this protocol for Cassandra 1.

So what if you want to give that new protocol a try? First, you need a version of Cassandra 1. Then, you need to activate the binary protocol server. Keep in mind that this protocol and its implementation are brand new. For that reason, the binary protocol server is not started by default only the thrift server is. Lastly, you need a client driver that support this new protocol. One such driver that is still beta itself is the Java Driver that DataStax open-sourced a few days ago.

We believe this new protocol is a good addition to Cassandra and it already offers a number of advantages asynchronicity, notifications, But I have two question: How many requests can each connection handle at the same time in new protocol?

In notification feature if a client add a new column to an existing row, will server notify client about adding new pair? But from the protocol point of view, we could allow notification for any kind of events, which means we may have data-related notification in the future.

Shahryar the binary protocol itself is obviously agnostic to any specific API. As said above, the only java driver for the binary protocol currently is probably the new Datastax Java driver that is still in beta. Unfortunately I need a. Cassandra Sharp updated 5 days ago https: FluentCassandra updated 2 days ago https: I would like to take advantage of a binary protocol supported in Cassanda 1.

I openned an issue for cassandra-pdo because CQL3 composite keys dont work: There is a sequence id in the protocole which allows you to reconcile the replies with the request. By the way its sequence id is not limited to it is an int Why limiting the number of simultaneous request on a single connection to only ?

Nonetheless, at the top level, thrift still exposes a purely synchronous RPC based API, which makes doing asynchronous client calls more awkward you still have to occupy one thread per-client. Not sure what made you think that. See the protocol specification. And no, data is not framed on disk, or at least not framed in the sense of the native protocol, but I do fail to see how that is relevant in any way?

Sylvain why did you decide to implement a new protocol from scratch, rather than trying to improve Thrift to meet your needs? Was that a lost cause? About the stream id, I was saying that in Thrift it is a int32, so you can have more than concurrent requests.

And I wonder why having limited the number of concurrent request to ? About data framing, I made the remark because it is faster to stream data asap than reading all of it to count the length, and start streaming. Or do I miss something?

Thanks for the blog, Sylvain. This article is fairly dated. I know Python cassandra driver 2. I wrote a PHP client for Cassandra, which uses a binary protocol. Look and please vote my work on github.
