Modern databases are moving to the cloud for elastic resource allocation and high availability. Cloud-native databases adopt a unique storage-disaggregation architecture, where the computation and storage are decoupled as two separate services connected through the data center network. The new storage-disaggregation architecture demands a revisit of database system design. In this talk, I first discuss our recent research on optimizing the two-phase commit protocol, a fundamental building block in distributed transactional databases. We leverage the disaggregated storage service to reduce the protocol latency and eliminate blocking. Then, I discuss our work on leveraging storage-layer computation (i.e., a pushdown layer) to accelerate data analytics processing.
