> So far, the native client communicates with insecure cluster.
> This JIRA is to add secure connection support for native client using Cyrus library.
> The work is based on earlier implementation and is redone via wangle and folly frameworks.
> Thanks to [~devaraj] who started the initiative.
> Here is high level description of the design:
> * SaslHandler is declared as:
> {code}
> class SaslHandler
>     : public wangle::HandlerAdapter<folly::IOBufQueue&, std::unique_ptr<folly::IOBuf>>{
> {code}
> It would be inserted between EventBaseHandler and LengthFieldBasedFrameDecoder in the pipeline (via ConnectionFactory::Connect())
> * SaslHandler would intercept writes to server by buffering the IOBuf's and start the handshake process (via sasl_client_XX calls provided by Cyrus)
> * after handshake is complete, SaslHandler would send the buffered IOBuf's to server and act as pass-thru from then on
