Atomic Transaction Commit for Modern Data Stores
IMDEA Software Institute in Madrid –
Modern data stores often need to provide both high scalability and strong transactional semantics. They achieve scalability by partitioning data into shards and fault-tolerance by replicating each shard across several servers. A key component of such systems is the protocol for atomically committing a transaction spanning multiple shards, which is usually integrated with concurrency control.
Unfortunately, the classical theory of atomic commit is too restrictive to capture the complexities of such protocols. I will present a new problem statement for atomic commit that more faithfully reflects modern requirements and will describe solutions to this problem in different classes of data stores, including those for geo-replication and those that exploit Remote Direct Memory Access (RDMA).
