Key Points
ESR allows to trade-off between consistency and performance
Consistency can be relaxed in a controlled and consentaneous way
ESR-DBSM is upper bounded by the strict locking policy and lower bounded by the snapshot
Without resorting to semantic specific epsilons overall latency in the DBSM can be reduce by 40%. A very small number of ESR conflicts contributes to this value
Abort rate for read-only transactions is almost eliminated
Revisiting ESR to improve the DBSM
Conclusion
