Abstract--Datastores are distributed systems that manage
enormous amounts of structured data for online serving and
batch processing applications. The NoSQL datastores weaken the
traditional relational and transactional model in favor of hori-
zontal scalability. They usually support concurrent operations
with demanding throughput and latency requirements which
may vary across different workload types. A typical tradeoff
between query handling and total update costs frequently leads
to design decisions that sacrifice query responsiveness for higher
update throughput. For this tradeoff, critical component at each
storage server is a storage layer that schedules data transfers
