Go Concurrency & Channels Training

Master Go’s powerful concurrency model with this comprehensive 3-day training. Learn how goroutines, channels, and sync primitives work together to build concurrent programs that are correct, efficient, and easy to reason about.

Training Details


Duration	3 days (24 hours)
Level	Intermediate
Delivery	In-person, Live online, Hybrid
Certification	N/A

Who Is This For?

Go developers ready to write concurrent code
Backend engineers building high-throughput systems
Systems programmers working with parallel processing
Developers debugging concurrency issues in Go applications
Team leads designing concurrent architectures

Learning Outcomes

After completing this training, you’ll be able to:

Design concurrent programs using goroutines and channels
Apply the select statement for multiplexing channel operations
Use sync primitives (Mutex, RWMutex, WaitGroup, Once, Pool)
Implement common concurrency patterns (fan-in, fan-out, pipeline, worker pool)
Use context for cancellation, timeouts, and request-scoped values
Detect and fix race conditions using the Go race detector

Detailed Agenda

Day 1: Goroutines and Channels

Module 1: Goroutines

The Go scheduler and the GMP model
Launching and managing goroutines
Stack growth and goroutine lifecycle
Hands-on: Build a parallel file scanner

Module 2: Channels Fundamentals

Unbuffered and buffered channels
Channel direction (send-only, receive-only)
Closing channels and range over channels
Hands-on: Implement producer-consumer with channels

Module 3: Select Statement

Multiplexing with select
Timeouts and non-blocking operations
Done channels and signaling
Hands-on: Build a concurrent HTTP poller

Day 2: Synchronization and Patterns

Module 4: Sync Primitives

sync.Mutex and sync.RWMutex
sync.WaitGroup for coordination
sync.Once for initialization
sync.Pool for object reuse
Hands-on: Build a thread-safe cache

Module 5: Concurrency Patterns

Fan-in and fan-out patterns
Pipeline pattern for data processing
Worker pool pattern
Semaphore pattern with buffered channels
Hands-on: Build a concurrent image processing pipeline

Module 6: Race Conditions and Debugging

Understanding data races
The Go race detector (-race flag)
Atomic operations with sync/atomic
Common concurrency bugs and fixes
Hands-on: Find and fix race conditions in existing code

Day 3: Context, Advanced Patterns, and Real-World Applications

Module 7: Context Package

context.Background and context.TODO
context.WithCancel, WithTimeout, WithDeadline
context.WithValue and request-scoped data
Propagating context through call chains
Hands-on: Add cancellation and timeouts to an HTTP server

Module 8: Advanced Concurrency Patterns

Error groups (golang.org/x/sync/errgroup)
Rate limiting with time.Ticker
Graceful shutdown patterns
Bounded parallelism
Hands-on: Build a rate-limited web crawler

Module 9: Real-World Concurrency

Designing concurrent APIs
Testing concurrent code
Performance considerations and benchmarking
When NOT to use concurrency
Hands-on: Capstone — build a concurrent task scheduler

Prerequisites
