03Install Kafka 4.3.x & Build a Reproducible Local LabCreate a repeatable Kafka lab using the current KRaft-based runtime and verify the minimum environment before experimenting.Beginner · 30 min readLockedLocked

04Topics, Partitions, Offsets & the Append-Only LogLearn the storage model that drives ordering, parallelism, replay, retention and consumer position.Beginner · 32 min readLockedLocked

06Producer Reliability: acks, Retries, Idempotence, Batching & CompressionConfigure producers for durability and throughput without accidental duplicates, reordering or hidden latency.Advanced · 42 min readLockedLocked

07Consumer Fundamentals: Poll Loop, Fetching, Position & Offset CommitsUnderstand the consumer poll model, current position, committed offsets and processing ownership.Intermediate · 38 min readLockedLocked

08Consumer Groups, Partition Assignment, Lag & ScalingLearn how traditional groups distribute partitions and how to interpret lag without confusing it with user latency.Intermediate · 36 min readLockedLocked

09Consumer Rebalancing: Classic vs Next-Generation Consumer ProtocolUnderstand rebalancing and the GA next-generation consumer protocol available in modern Kafka.Advanced · 40 min readLockedLocked

10Share Groups: Queue-Like Cooperative Consumption in Modern KafkaLearn production-ready share groups, record acknowledgements and where their queue-like model differs from traditional consumer groups.Advanced · 40 min readLockedLocked

11Replication: Leaders, Followers, ISR, High Watermark & Leader ElectionUnderstand how partition replicas provide availability and how ISR membership affects acknowledged writes and failover.Advanced · 42 min readLockedLocked

12Durability Engineering: min.insync.replicas, acks & Data-Loss BoundariesDesign topic and producer durability together so failures reject unsafe writes rather than silently lowering guarantees.Advanced · 40 min readLockedLocked

13Retention, Log Compaction, Tombstones & Replay WindowsControl record lifetime and use compaction correctly for key-based latest-state streams.Intermediate · 36 min readLockedLocked

14Kafka Storage Internals: Segments, Indexes, Page Cache & Disk LayoutUnderstand storage internals so disk pressure, retention and latency symptoms are easier to reason about.Advanced · 40 min readLockedLocked

15Ordering Guarantees & Partitioning StrategyDesign keys and partitions around the exact scope of business ordering rather than assuming global order.Intermediate · 34 min readLockedLocked

16Serialization, Schemas & Compatibility GovernanceTreat event schemas as long-lived APIs between independently deployed producers and consumers.Intermediate · 38 min readLockedLocked

17Delivery Semantics: At-Most-Once, At-Least-Once & Exactly-Once BoundariesUnderstand where duplicates or loss can occur and never say exactly once without naming the boundary.Advanced · 42 min readLockedLocked

18Kafka Transactions: Atomic Writes, Offset Commits & read_committedUse transactional producers for Kafka-native atomicity and understand transactional IDs, fencing and consumer isolation.Advanced · 44 min readLockedLocked

19Retry Topics, Dead-Letter Patterns & Poison MessagesDesign failure handling without infinite hot loops, hidden data loss or broken ordering assumptions.Advanced · 38 min readLockedLocked

20Event Design: Facts, Commands, IDs, Timestamps & ContractsModel durable events that remain understandable after the producing code and database have changed.Intermediate · 36 min readLockedLocked

21Topic Design: Naming, Ownership, Partitions, Replication & DefaultsTurn Kafka topics into governed production interfaces with explicit ownership, capacity, durability and lifecycle decisions.Intermediate · 40 min readLockedLocked

22Partition Count & Capacity PlanningSize partitions from throughput, consumer parallelism, ordering boundaries and operational overhead instead of arbitrary round numbers.Advanced · 45 min readLockedLocked

23Kafka Networking: listeners, advertised.listeners, DNS & Client ConnectivityUnderstand the two-address problem that causes many Docker, Kubernetes, cloud and hybrid Kafka connectivity failures.Advanced · 44 min readLockedLocked

24KRaft Operations: Controller Quorum, Dynamic Membership & Metadata HealthOperate modern Kafka metadata safely: understand controllers, quorum state, voter health and KRaft failure boundaries.Advanced · 48 min readLockedLocked

25Kafka CLI Administration: Topics, Configs, Groups, Offsets & Log DirectoriesUse Kafka's administration tools as evidence-producing instruments instead of dangerous copy/paste commands.Intermediate · 46 min readLockedLocked

26Kafka Security: TLS, SASL, ACLs & Least PrivilegeBuild authenticated, encrypted and authorized Kafka traffic without turning every client into a cluster administrator.Advanced · 52 min readLockedLocked

27Multi-Tenancy, Quotas & Noisy-Neighbor ControlKeep shared Kafka clusters predictable when teams, clients or workloads compete for broker and network capacity.Advanced · 38 min readLockedLocked

28Monitoring Kafka: Broker, Producer, Consumer & KRaft SignalsMonitor Kafka as an end-to-end streaming system: brokers, controllers, clients, replication, storage and business flow.Advanced · 50 min readLockedLocked

29Consumer Lag Deep Dive: Backlog, Time Lag, Hot Partitions & StallsInterpret lag as a symptom with rate, age and partition context instead of one scary integer.Advanced · 45 min readLockedLocked

30Broker & Storage Performance EngineeringTune brokers from measured bottlenecks across disk, page cache, network, request handlers, replication and partition placement.Advanced · 50 min readLockedLocked

31Producer Performance Tuning: Batch, Linger, Compression & BackpressureIncrease producer throughput without trading away latency, durability or application stability unintentionally.Advanced · 44 min readLockedLocked

32Consumer Performance: Fetch Tuning, Processing Parallelism & BackpressureScale consumers without breaking poll-loop liveness, offset correctness or downstream dependencies.Advanced · 46 min readLockedLocked

33Kafka Connect: Source/Sink Connectors, Workers, Tasks & Offset StateUse Kafka Connect as an operated integration runtime with clear worker, task, converter, offset and failure semantics.Advanced · 48 min readLockedLocked

34Kafka Streams: Stateless/Stateful Processing, Repartition & State StoresBuild event-processing applications that understand keys, state stores, changelogs, repartitioning and recovery.Advanced · 52 min readLockedLocked

35Change Data Capture (CDC) Architecture with KafkaDesign database-to-Kafka change streams without confusing low-level row changes with durable domain contracts.Advanced · 45 min readLockedLocked

36Multi-Cluster Kafka & MirrorMaker 2Replicate selected streams across clusters while explicitly handling failover, offsets, loops and consistency expectations.Advanced · 50 min readLockedLocked
