1. Home of Redis What’s New with Enterprise Redis Leena Joshi
2. 2 Agenda • What is Enterprise Redis? • Redis on Flash • Redis and Spark • Redis Module Hub
3. 3 Enterprise Conjures Up.. OR
4. 4 But What It Really Means Is:
5. 5 Which In Turn Means: Infinite Seamless Scaling True High Availability Top notch expert support
6. 6 Redis Labs Enhances OSS Redis Redis Labs Node Open Source Zero latency proxy Cluster Manager REST API Odd number of nodes needed to handle network splits- not three copies of data Redis Labs Cluster • Shared nothing cluster architecture • Fully compatible with open source commands & data structures Proprietary
7. 7 The Same Technology Runs Redis Cloud Cluster Management Path Proxies Node Watchdog Cluster Watchdog Node 1 Node 2 Node N (uneven number) … Redis Shards Unique multi-tenant “Docker” like architecture enables running hundreds of databases over a single, average cloud instance without performance degradation and with maximum security provisions Data Path Distributed Proxies Single or Multiple Endpoints 50,000+ Customers
8. 8 Tremendous Customer Traction Redis Cloud Available since mid-2013 6000+ enterprise customers Redis Labs Enterprise Cluster (RLEC) Available since early-2015 100+ enterprise customers
9. 9 Always On - Highly Available & Persistent Simple, Seamless Clustering. Linear Scalability. Enterprise-Class Management and Support Enterprise-Class Redis – The Benefits Stable & Predictable Top Performance Operational Cost Savings
10. 10 Simple, Seamless Scaling and Clustering Auto- scaling/re-sharding/re-balancing No downtime while scaling Supports cross-shard operations Simple, Seamless Clustering. Linear Scalability. Linear Scalability
11. 11 Always On - Highly Available & Persistent Seamless cross datacenter/region/cloud replication Instant auto-failover Persistence, backups and DR Always On - Highly-Available & Persistent
12. 12 Stable & Predictable Top Performance Consistent high performance achieved under any load or cluster size Database processed by multiple cores Built-in performance enhancement techniques Stable & Predictable Top Performance
13. 13 Operational Cost Savings OSS Redis Redis Labs More efficient hardware utilization: fewer servers, lower power & cooling and operational costs Reduced manual labor through automation - reduced time writing scripts, scaling, configuration, monitoring, re-balancing and more Run Redis on flash memory as RAM extender – up to 10 times cheaper Reduced downtime incidents Shorten time to deploy Redis by over 50%
14. 14 Enterprise Management and Support UI, CLI, REST API -based management & alerting Proven technology supporting thousands of customers 24x7 enterprise support, top notch Redis expertise Enterprise-Class Management & Support
15. 15 Redis Labs: Fastest Recovery, No Data Loss % of times data was lost Average time to recover in seconds Redis Labs recovers in 5 seconds and does not lose data. All other vendors lose data and take many minutes to recover Vendors evaluated include (not in order) • Heroku Redis • AWS ElastiCache • Microsoft AzureCache • Compose.io
16. 16 Redis Labs: The Only True HA Redis 16 Failure Event In-memory Replication Multi-DC/Zone replication Auto-failover AOF Data Persistence Backup (using snapshots) Multi- region/Cloud replication Process failure Instant recovery* Slow recovery Node failure Instant recovery* Slow recovery Multi-node failure Instant recovery* Network split Instant recovery* Zone/Rack failure Instant recovery* Slow recovery Fast recovery Region/Cloud failure Slow recovery Fast recovery Type of outage Essential features for high availability *Auto-failover should run on same nodes as Redis deployment Redis Labs provides all the essential HA features that protect against every type of outage
17. Redis on Flash
18. 18 Why Analyze Data In-Memory? “Information is the oil of 21st century, and analytics is the combustion engine”- Peter Sondergaard, Gartner Analyst
19. 19 Decision Speeds Are Accelerating.. “Big Data” gains popularity as tools become available to harness it Batch insights start to drive business Real time insights automate decision- making 2005 2012 - 2015 2016… THE DATA REVOLUTION IS MATURING..
20. 20 The Race Is On.. INSIGHTS FROM YOUR DATA NEED TO BE INSTANTANEOUS COST EFFECTIVE
21. 21 Price/Performance of Memory Technology
22. 22 Redis on Flash Flash used as a RAM extender and NOT as persistent storage
23. 23 Redis on Flash Concepts • Flash used as a RAM extender (NOT as a persistent storage) • Global key list in RAM; ‘hot’ values in RAM; ‘cold’ values on Flash. • Multi-threaded & async Redis when accessing objects on Flash. Utilizes multi-core and Flash concurrency architecture • 100% compatibility with Redis
24. 24 How to Achieve Optimal Price/Performance By dynamically setting RAM/Flash ratio
25. 25 Single Server Results with Dell & Samsung NVMe read write read write Avg: 2.04M ops/sec Max: 2.14M ops/sec Avg: 0.91msec Max: 0.98 msec % below 1msec: 100% Avg: 313RMB / 9.4WMB Max: 1.71RGB / 96WMB Avg: 1.45Gbps (Tx) / 0.97Gbps (Rx) Max: 1.6Gbps (Tx) / 1.2Gbps (Rx) Test setup: • Redis Labs Enterprise Cluster v3.2 • Dell Xeon CPU E5- 2670 v3 @ 2.50GHz • 4x Samsung NVMe PM1725 • Memtier benchmark- open source tool • 100B object size • 80% read • 20% write Throughput – ops/sec Latency – msec Disk Bandwidth – MB/sec NW Bandwidth – Gb/sec >2M Ops/sec, <1 ms latency, > 1GB disk bandwidth
26. 26 A Real Life Example With Redis On Flash Customer Scenario: • Genome dataset • Key sizes: 32B, value sizes : 5-12B • No of keys: 250 x109… 250 x1012 Key1: AAAAAAAAAAAAAAAAAAAAAAAACCCCAAA Value1 = Freq=4 IE=A OE=A Key2: AAAAAAAAAAAAAAAAAAAAAAAAACAACCC Value2 = Freq=7 IE=A,C,T,G OE=A,C,T,G *IE – Inside End sequences *OE – Outside End sequences
27. 27 Optimizing Redis Usage RAW • # of keys 250x10^9 • Key size = 32B • Value size = 8B (average) • Overhead per object (key+value) = ±61B (key) + 9 (value) = 70 • Internal fragmentation per object = 14B • RAM size = ±31TB
28. 28 Further Optimizations Encoding keys and values to compress sizes • # of keys 1.25x10^9 • Key size = 4B • Value size = 3612B • RAM overhead per object (key+value) = ±40B • RAM size = ±55GB // for optimal performance we used 500GB to keep 10/90 RAM/Flash ratio • Flash size = ±4.5TB Using Redis Hashes to store compressed keys/values (200 keys and values per hash) 1 2
29. 29 Memory Usage and Cost Comparison Redis on RAM Strings Redis on Flash Hashes RAM size 31TB 0.5 TB Flash size - 4.5TB EC2 instances 155 x r3.8xlarge 2 x i2.8xlarge 1yr costs (reserved instances) $2,017,325 $49,862 Savings with Flash & Hashes % 97.6%
