TAO is Facebook’s read-optimized, distributed graph data store, which was recently extended to support failure atomic write transactions. Because TAO does not yet support read transactions, developers must reason about and explicitly handle fractured reads (that reflect partial transaction updates). To provide atomic visibility (wherein reads observe all or none of a transaction’s operations), Cheung et al. present a new RAMP-TAO protocol, which protects against fractured reads for recently transactionally updated data without significantly impacting TAO’s reliability and efficiency. RAMP-TAO can provide default guarantees across data stores and can be applied retroactively to optimize other similar eventually consistent systems that need stronger isolation models.
