  16. Turnkey Global Distribution Elastic scale out of storage and throughput

  17. Turnkey Global Distribution Elastic scale out of storage and throughput Guaranteed 99th percentile low latency Prefix Strong Bounded Staleness Session Eventual <10ms <10ms Indexed Writes (1 KB) <10ms + 2RTT <10ms <10ms <10ms <10ms <10ms <10ms <10ms Reads (1 KB)

  18. Turnkey Global Distribution Elastic scale out of storage and throughput Guaranteed 99th percentile low latency Five well-defined consistency models Learn more: Session Bounded-stateless Eventual Consistent prefix Strong https://jlik.me/c6b

  19. Turnkey Global Distribution Elastic scale out of storage and throughput Guaranteed 99th percentile low latency Five well-defined consistency models • Guaranteed latest version of reads • Highest consistency • Lowest performance • Lowest availability • 2x cost of Session -> Eventual Session Bounded-staleness Eventual Consistent prefix Strong

  20. Turnkey Global Distribution Elastic scale out of storage and throughput Guaranteed 99th percentile low latency Five well-defined consistency models • Consistent within a time frame (i.e. 5 minutes old) • Better performance • Low availability • 2x cost of Session -> Eventual Session Bounded-staleness Eventual Consistent prefix Strong

  21. Turnkey Global Distribution Elastic scale out of storage and throughput Guaranteed 99th percentile low latency Five well-defined consistency models • Consistent for the session • Always read own writes • Other data ordered but not guaranteed current • Good performance • Good availability Session Bounded-staleness Eventual Consistent prefix Strong

  22. Turnkey Global Distribution Elastic scale out of storage and throughput Guaranteed 99th percentile low latency Five well-defined consistency models • Read is consistent to a point in time • No guarantee how current • Good performance • Excellent availability Session Bounded-staleness Eventual Consistent prefix Strong

  23. Turnkey Global Distribution Elastic scale out of storage and throughput Guaranteed 99th percentile low latency Five well-defined consistency models • No guaranteed ordering/freshness of data • Eventually “catches up” • Highest performance • Highest availability Session Bounded-staleness Eventual Consistent prefix Strong

  24. Demo: Consistency Levels

  25. Turnkey Global Distribution Elastic scale out of storage and throughput Guaranteed 99th percentile low latency Five well-defined consistency models Throughput Consistency Latency HA Comprehensive SLAs <10ms Guaranteed Guaranteed 99thpercentile 99.99%
