nodejsDiagnosing Vitess VTGate Routing Failures by Keyspace and Shard
Application queries intermittently fail with VTGate routing errors like unknown keyspace or no healthy tablet? This guide walks through ordered checks, cause tables, and fixes tied to findings.
vitessChoosing a Sharding Strategy for Memcached Clusters
Avoid cache stampedes when scaling Memcached. This guide compares modulo sharding vs. consistent hashing (Ketama/HRW) to minimize key redistribution during cluster changes.
Diagnosing discord.js v14 Sharding Failures: Missing Guilds, Error 1009, and Silent Presence Loss
Sharding bugs in discord.js v14 usually come down to shard count math, missing privileged intents, or inconsistent config across processes. Here's how to diagnose each failure mode and verify the fix.
Choosing the Right Vitess Vindex: Hash, Lookup, Range, or Numeric for Your Sharding Key
A decision guide for choosing Vitess Vindex types (hash, lookup, range, numeric) based on cardinality, query patterns, and resharding needs. Includes a comparison table, trade-off analysis, and a concrete VSchema implementation with validation steps.
Diagnosing Yellow/Red Cluster Health in Elasticsearch: Unassigned Shards, Sharding, and Replication
When an Elasticsearch cluster turns Yellow or Red, unassigned shards are usually the culprit. This guide walks through the diagnostic steps, root causes, and targeted fixes—covering shard counts, replica settings, and allocation rules—to bring your cluster back to Green.

Learn how to pick the right Playwright parallelization level—worker pool, test sharding, or project isolation—to cut CI run time while keeping tests deterministic. Includes a comparison table, trade‑offs, and a concrete example.
Designing a Minimal YugabyteDB Cluster: Tablets, Raft, and the Decisions That Matter
An architecture note on the smallest YugabyteDB cluster worth running: three nodes, three zones, RF 3, with tablets as Raft groups. Covers placement flags, operational checks, and the failure modes that should trigger a redesign.
