SUMMARY:PhD Seminar • Generalized Transaction Durability Model
CLASS:PUBLIC
DESCRIPTION:JAEMYUNG KIM\, PHD CANDIDATE\nDavid R. Cheriton School of Compu
 ter Science\n\nTransaction durability guarantees the ability to recover co
 mmitted\ntransactions from failures. However\, making every transaction du
 rable\nimpacts transaction processing performance. Some ad-hoc durability\
 nmechanisms (e.g.\, delayed durability) improve performance\, but they\nri
 sk transactions losing their effects due to failures. The current\none-siz
 e-fits-all transaction durability model does not solve this\nproblem. We p
 ropose a new generalized transaction durability model to\ntrade-off perfor
 mance and durability and argue that transactions\nshould also provide flex
 ible durability like they provide multiple\nisolation levels. We evaluate 
 the performance of a modified PostgreSQL\nthat supports the new durability
  model using a micro-benchmark to show\nthe durability/performance trade-o
 ffs.
