Thanks @kylebarron , let me know when the PR is ready!

I assume the breaking changes from updating thrift (see #18) aren't desired? So we need to figure out a way to use thrift 0.13, right?

Any suggestions there? I assume figuring out their docker setup is the easiest approach

[kylebarron]

I was able to build the docker image for thrift 0.13, so I think this PR should be good to review now.

LGTM. Thanks @kylebarron !

I assume the breaking changes from updating thrift (see #18) aren't desired? So we need to figure out a way to use thrift 0.13, right?

I think we can still upgrade Thrift to the latest version in a separate PR, and bump up the major version after that. Thrift 0.13 is a bit old now.

[kylebarron]

It seemed from #18 that there wasn't consensus over whether to upgrade.

I figured the easier approach would be to upgrade the thrift definitions while still using thrift 0.13, because then we can sidestep for now the decision of whether upgrading the thrift compiler version is worth it.

Sounds good. Merged!
