> Currently, we have ZK and HMS based Lock providers, which can be limited to co-ordinating across a single EMR or Hadoop cluster. 
> For aws users, DynamoDB is a readily available , fully managed , geo replicated datastore, that can actually be used to hold locks, that can now span across EMR/hadoop clusters. 
> This effort involves supporting a new `DynamoDB` lock provider that implements org.apache.hudi.common.lock.LockProvider. We can place the implementation itself in hudi-client-common, so it can be used across Spark, Flink, Deltastreamer etc.
