9. IN-MEMORY DATA STRUCTURE
• Expensive (RAM Price)

10. IN-MEMORY DATA STRUCTURE

11. IN-MEMORY DATA STRUCTURE
And alse, We need
• Atomicity
• Easy & Fast Support
• Change & Upgrade [Smoothly]
Solution(s)
• Stack Overflow (last answer)
• Twitter (also uses Memcached to store 15
month-old tweets)
• AT&T – (customer support)

12. How to benefit
[Redis] ?04

13. IN-MEMORY DATA STRUCTURE
• Redis is the proven product
• Read [fast]
• Write [faster]
• Bulk Insertion
• Use REST API
• Atomicity
• Similar Structure, supports data structures
• Strings, Hashes, Lists, Sets, Sorted Sets with range queries
• Bitmaps, Hyperloglogs
• Geospatial indexes with radius querie
• Replication, Transaction [like Rollback], different levels of on-disk persistence,
Cluster Solution

14. • NoSQL
• Data Models (Need-Based)
• Back-up
• Backward_Compatibility
IN-MEMORY DATA STRUCTURE

15. Top 5 Redis use cases *
• Session Cache
• Full Page Cache (FPC)
• [to use Magento]
• Queues
• in memory storage engine to do list
and set operations
• Leaderboards/Counting
• Sets and sorted sets
• Ex: So to pull the top 10 users
from a sorted set
• Pub/Sub
• Ex: Social network connections events

IN-MEMORY DATA STRUCTURE

16. Conclusion
• Suitable for cache if RAM is not issue
• Infrastructure will not commodity hardware
• Distributed and Centralizes as Service
• Better than Mem-cache
• Near Real Time Cache
