Is this a video course?

No. This is an interactive, slide-based learning platform. Each lesson has rich text, animated diagrams, live code editors, and quizzes. You learn by reading, interacting, and doing, not by watching videos passively.

How long do I have access?

Forever. Both pricing tiers are one-time payments with lifetime access. This includes all current 766 lessons and any future content we add.

What level of experience do I need?

None. We start from absolute basics like 'What is latency?' and build up to distributed consensus protocols. The Foundation level assumes zero prior knowledge of system design.

How much does the system design course cost?

7.99 US dollars for lifetime access globally, or 499 Indian rupees for lifetime access in India. One-time payment, no subscription, no hidden fees. 11 lessons are free with no signup required.

What technologies are covered?

Everything from DNS and load balancers to Kubernetes, Kafka, distributed databases, consensus protocols, stream processing, security architecture, and observability. We cover principles and real-world implementations used at Netflix, Google, Amazon, Uber, Stripe, and more.

Is this useful for system design interview preparation?

Yes. The lessons are structured around the exact topics asked in system design interviews at FAANG and top-tier companies. Interactive diagrams help you practice whiteboard-style explanations. Covers everything from URL shortener design to distributed payment systems.

How is this different from ByteByteGo or Educative?

766 interactive lessons (4x more than most competitors), 16 different diagram types that build step by step, real production examples from Netflix, Google, Amazon, Uber, and Stripe, and lifetime access for a one-time payment of $7.99 instead of annual subscriptions costing 100 to 200 dollars per year.

What's the fundamental difference between a regular view and a materialized view?

A materialized view stores the query result on disk and serves reads from that snapshot, while a regular view re-executes the query on every read, A regular view is just a saved query, it re-runs on every SELECT. A materialized view computes the result once, stores it on disk like a table, and serves reads from that stored data. It's a snapshot that needs explicit refreshing.

Why is the CONCURRENTLY option important when refreshing a materialized view in production?

Without CONCURRENTLY, the view is locked during refresh, no reads can happen. CONCURRENTLY allows reads of the old data while the new data is computed, Without CONCURRENTLY, a refresh takes an exclusive lock on the materialized view. Any query trying to read it during refresh will block and wait. In production with active users, this is unacceptable. CONCURRENTLY serves the old data while computing the new data, then swaps atomically.

A materialized view's underlying query takes 45 seconds. The team wants to refresh every minute. What's the problem?

The database spends 45 out of every 60 seconds rebuilding the view, consuming 75% of its resources on refresh alone, If the refresh takes 45 seconds and runs every 60 seconds, the database is spending 75% of its time just on this one view. Either optimize the underlying query, refresh less frequently (every 15-30 minutes), or consider a different approach like incremental materialization.
