TODO for SOSP Camera Ready

• 1 M client benchmark / cstlee

• Full-mix for TPC-C benchmark / seojin

• Measure 1-level deeper for throughput (factor analysis?)
• Clarify the term linearizability: make proposals. / collin
• Talk about ultimate client / John??
• Clarify exp setup for TPC-C benchmark.
• Comparision with tell from VLDB.
• Extra paragraph lease

Tentative schedule for both linearizability and TX.

...

• Prep Rpc and Handling - Seojin / DONE!
• Client driven transactions "task" - Collin / 3 days (John said 2 weeks.)DONE!
• Transaction object & API - 2daysCollin /  DONE!
• Multiple objects per prepare RPC - DONE!

Transaction Cleanup Coordinator (Recovery Coordinator)

• Timer and Rpc for initiating recovery protocol. - Seojin / Half DONE.
• Request Abort Rpc and Handling - Seojin / 2 day
• Transaction Cleanup "task" - Collin / 3 days DONE!
• Transaction Cleanup crash recovery - Collin / 2 days DONE!

Common Components (Mostly in Data Master)

• Decision Rpc - seojin / DONE!
• lock table - Collin / DONE!
• Special GC rules for transaction entires (& lease expiration handling) - Seojin / 3 day
• Transaction log records & recovery - Seojin / DONE!

...

• Run TPC-C and compare with other systems (eg. H-store)
• YCSB?
• Ask Ankita and SYang
