Introduction to Redis

In the Introduction to Redis training course, you'll learn:

Introduction to Redis

• Redis compared to other databases and software
• Features
• Why Redis?

What Redis Data Structures Look Like

• Strings in Redis
• Lists in Redis
• Sets in Redis
• Hashes in Redis
• Sorted sets in Redis

Redis Web Applications

• Login and cookie caching
• Shopping carts in Redis
• Web page caching
• Database row caching
• Web page analytics

Commands in Redis

• Strings
• Lists
• Sets
• Hashes
• Sorted sets
• Publish/subscribe
• Sorting
• Transactions
• Expiring keys

Data Management

• Persistence options
• Snapshots
• Append-only file persistence
• Rewriting/compacting append-only files
• Replication
• Configuring for replication
• Controller/agent chains
• Verifying disk writes
• System failures

Application Support

• Logging to Redis
• Counters and statistics
• Service discovery and configuration
• Using Redis to store configuration information

Application Components

• Distributed locking
• Fine-grained locking
• Locks with timeouts
• Counting semaphores
• Fair semaphores
• Refreshing semaphores
• Preventing race conditions
• Task queues
• Distributing files with Redis

Search-based Applications

• Searching in Redis
• Basic search theory
• Sorting search results
• Sorted indexes
• Sorting search results with ZSETs

Reducing Memory Use

• Short structures
• The ziplist representation
• The intset encoding for SETs
• Performance issues for long ziplists and intsets
• Sharded structures
• HASHes
• SETs

Scaling Redis

• Scaling reads
• Scaling writes and memory capacity
• Handling shard configuration
• Creating a server-sharded connection decorator
• Scaling complex queries
• Scaling search query volume
• Scaling search index size
• Scaling a social network
