Why is Thrift transport deprecated, and what should I use instead?

About a year and a half ago, I worked on a project that used elasticsearch-py, and I remember we saw an order-of-magnitude decrease in query round-trip time when we used the thrift transport.
I'm now working on a different project and coming back to elasticsearch, and I see that thrift is being deprecated, according to this.
Should I use a different transport instead? Will I be able to achieve the same speed that I got with Thrift?
Thanks
