Databricks Streaming Guardian

Category: General  ·  Sub-category: automation  ·  Last updated:
Guard production Databricks data pipelines — Delta Lake, Liquid Clustering, Structured Streaming, Auto Loader, and DLT — against the twelve foot-guns that fire at scale: OPTIMIZE/auto-compaction conflicts, Liquid-Clustering merge conflicts, VACUUM breaking a streaming checkpoint, RocksDB OOM, Auto Loader schema-evolution stops, and DLT refresh data loss. Includes a PreToolUse hook that blocks DROP/CREATE-OR-REPLACE/VACUUM on a table with active streaming consumers. Use when a Delta MERGE/OPTIMIZE fails with a concurrency exception, a stream breaks after VACUUM or a table replace, an Auto Loader stream stops on a new column, a DLT refresh drops data, or before running a destructive op on a streamed-from table. Trigger with "ConcurrentAppendException", "ConcurrentDeleteDeleteException", "DELTA_FILE_NOT_FOUND", "streaming checkpoint broke", "vacuum broke my stream", "autoloader UnknownFieldException", "dlt full refresh".

From the source SKILL.md

The data-ops spine of the pack. Delta Lake, Liquid Clustering, Structured Streaming, and DLT each ship a different set of foot-guns that fire most visibly when production data flows through them at scale — and most of them are documented platform decisions that surprise engineers, not bugs. This skill's job is friction at trigger time (a hook that blocks the genuinely-irreversible op) plus deterministic recovery when something already broke.

What this skill does

Databricks Streaming Guardian is a community-contributed Claude Code skill in the automation sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/databricks-streaming-guardian/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when a Delta MERGE/OPTIMIZE fails with a concurrency exception, a stream breaks after VACUUM or a table replace, an Auto Loader stream stops on a new column, a DLT refresh drops data, or before running a destructive op on a streamed-from table. Trigger with "ConcurrentAppendException", "ConcurrentDeleteDeleteException", "DELTA_FILE_NOT_FOUND", "streaming checkpoint broke", "vacuum broke my stream", "autoloader UnknownFieldException", "dlt full refresh".

Who uses this skill

The Databricks Streaming Guardian Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 151,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
