             Summary: Implement async versions of the table API 
                 Key: SAMZA-1763
                 URL: https://issues.apache.org/jira/browse/SAMZA-1763
             Project: Samza
          Issue Type: Improvement
            Reporter: Peng Du
            Assignee: Peng Du


In Samza, Table API provides a consistent and simple way to perform IO with 
non-stream data sources, eg. key-value stores. It can be used in high-level API 
in the form of stream-table join and sendTo operators. Low-level API 
integration is also being worked on. 

The current set of Table APIs only consists of synchronous versions in that all 
calls are blocking. Unlike local tables, there is a strong need to have async 
for remote tables to deliver higher throughput which can otherwise be hindered 
with full sync executions. 

Given there is currently no async support in Samza high-level API, the design 
in this document is mainly targeted for low-level API.
