> I was recently working on some potential usage of gRPC in Oak. I'll create an
> issue shortly, explaining the idea. For now, I'd like to use the gRPC in the
> same class loader as Azure Data Store. The gRPC uses Guava 26 and can't be
> downgraded. In Oak, we're using Guava 15.
> We'll probably upgrade the Oak to Guava 26 in the future, but it'll be a
> bigger task. I was wondering if there's a workaround that allows to use APIs
> which are common to Guava 15 and 26 in the Azure Data Store. It seems that
> we're using the APIs removed from Guava 26 just in two places of the
> UploadStagingCache class:
> * in the file traverser in UploadStagingCache#build()
> * in the future handling in UploadStagingCache#stage()
> [~amitjain], I was wondering if you'd be OK with changing these two places,
> so they are compatible both with Guava 15 and 26. It'd help me with
> proceeding with the PoC I mentioned. And again: the current version works
> completely fine.
> For the file traversing, we can use the Java 8 file traverse utils. For the
> future listening, I copied the SameThreadExecutorService from Guava and used
> it as an extra parameter, required in the newer versions.
> WDYT?
