-----------------------------------
Hello, what's the status of this ticket? It seems blocked for a while.
Thrift 0.9.3 is quite old as version, and every time when we find something to
fix in it (bug, vulnerabilities, etc), we need to ask thrift community to
backport the patch to 0.9 branch, which creates burdens on both projects.
It would be nice to move forward.
> Upgrade thrift to at least 0.10.0
