Phoenix has no CREATE MATERIALIZED VIEW statement — the supported equivalent is a view with a covering index. Here's how the mechanism works, a worked example, and the pitfalls.
Learn how to mount a LiveView, handle state, and prepare for high‑traffic production with Phoenix 1.7+. The guide covers prerequisites, a step‑by‑step setup, debugging tips, and recovery strategies.
Learn how to architect Phoenix Channels for real‑time apps: isolate state, enforce data boundaries, monitor PubSub, and handle failures. Includes a concrete persistent chat example and guidelines for scaling.
Phoenix LiveView can delete your duplicated validation and state layer — for the right features. A worked form example, its test, and the line where LiveView stops fitting.
Phoenix LiveView lets Ecto changesets power real-time form validation over a WebSocket — no client-side JavaScript. A worked registration form example, plus latency and state trade-offs.
Learn how to use Apache Phoenix Materialized Views to shift heavy aggregation costs from read-time to write-time, reducing HBase scan latency for analytical queries.
Ecto.Multi lets Phoenix developers bundle multiple database operations into a single transaction. This guide shows how to build a Multi, debug failures, and understand performance trade‑offs for atomic user‑signup flows.
Phoenix OFFSET-LIMIT pagination becomes inefficient for large offsets due to linear scan overhead. Keyset pagination using WHERE clauses on indexed columns provides better performance for deep paging.
Learn how to add a Phoenix secondary index to an HBase table, verify that the planner uses it, and weigh the read‑speed gains against write‑amplification and storage costs.
