Transaction Scheduling Replication Management

SLIDE 3

Lower Inter-Partition Transaction Coordination Costs

SLIDE 4

Rearranged Transaction Execution Pipeline

1) Logging 2) Scheduling 3) Execution

SLIDE 5

Log is Ultimate Source of Truth

SLIDE 6

Advantages

1) Near-Linear Scalability

SLIDE 7

No Distributed Commit Protocols Are Required

SLIDE 8

Advantages

1) Near-Linear Scalability 2) Strong Consistent Replication

SLIDE 9

Once a transaction is written to the log, no further inter replica coordination required to sync

SLIDE 10

Advantages

1) Near-Linear Scalability 2) Strong Consistent Replication 3) Highly Modular System Architecture

SLIDE 11

Calvin provides other system components with a declarative specification of the concurrency control

SLIDE 12

1) Log 2) Scheduler 3) Storage Back End

SLIDE 13

Advantages

1) Near-Linear Scalability 2) Strong Consistent Replication 3) Highly Modular System Architecture 4) Main-Memory OLTP performance over disk-resident data

SLIDE 14

All relevant data will be memory-resident

nce the transaction begins executing

SLIDE 15

Calvin

1) Deterministic 2) Highly Scalable 3) Good backup/replication when crash 4) Highly modular
