agent timed out when agent tried to run great expectations checkpoint on

Not specified by the original author.

TL;DR

Stop scanning the full warehouse in one checkpoint run: give the agent a bounded batch, such as the latest partition or a sampled batch with explicit sampling parameters, checkpoint progress per expectation, and raise the run timeout only after the batch is bounded. A checkpoint that must finish inside an agent timeout has to be sized to the timeout, not the other way round.

agent timed out when agent tried to run great expectations checkpoint on full warehouse scan

Use this when

• The check or run fails with this symptom: the agent's checkpoint run times out before validation completes.
• You are working on an agent running a Great Expectations checkpoint that times out on a full scan and the failure repeats on the same data or configuration.
• You need the failing rows, rule, or stage isolated before changing thresholds or code.

Not for this skill when

• A human-run checkpoint with no agent timeout, where batch sizing is a performance concern rather than a failure instead.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Record the batch the checkpoint tried to load: table size, partition range, and whether a filter or sampler was applied. Verify: the attempted batch scope is documented
2. Change the agent's run plan to validate the latest partition or a defined sample, passing batch parameters explicitly instead of the whole table. Verify: the agent's next run uses a bounded batch
3. Add per-expectation progress logging so a timeout leaves a record of what completed and what did not. Verify: progress is recorded per expectation during the run
4. Set the agent timeout from a measured run on the bounded batch, with headroom, rather than a global default. Verify: the timeout is derived from a measured bounded run
5. Run the bounded checkpoint end to end inside the timeout and confirm results are stored for every expectation. Verify: the checkpoint completes and all results are stored

Variant phrasings

agent timed out great expectations checkpoint full scan

The verbatim agent-checkpoint phrasing.

great expectations checkpoint too slow partition batch

The partitioning phrasing for bounded batches.

agent checkpoint timeout sampled validation run

The sampling phrasing for representative batches.

Compatibility: Great Expectations checkpoints run by an agent on warehouse-scale tables

Why it happens

Checkpoints validate whatever batch they are handed, and an agent that hands over an entire warehouse table turns a validation job into a full scan. Agent runtimes enforce wall-clock limits that batch warehouse jobs do not, so the unbounded batch and the fixed timeout collide predictably.

Edge cases / pitfalls

• Sampling must be deterministic for a given batch so reruns compare like with like.
• Keep one periodic full-table validation outside the agent loop so sampling never becomes the only coverage.

TL;DR

Fix this in BigQuery by acting on the exact message first: check whether the server finished despite the client timeout, split the work into smaller dated or scoped chunks, and resume from a checkpoint. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

agent timed out when agent tried to query BigQuery metrics error timeout failure

Use this when

• The operation in BigQuery fails with this exact message: agent timed out when agent tried to query BigQuery metrics error timeout failure.
• The same failure repeats on retry with unchanged inputs.
• A review, export or check is blocked until this item completes.

Not for this skill when

• The message is a permission or outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in BigQuery, and copy the full message plus the item, user or metric involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: check whether the server finished despite the client timeout, split the work into smaller dated or scoped chunks, and resume from a checkpoint. Verify: complete one chunk inside the time limit and confirm the checkpoint advances.
3. Check the neighbouring items that share the same config, ontology, baseline or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in BigQuery on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
5. Compare the result counts, decisions or alerts against the source in BigQuery so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

The server work grows with scope while the client timeout does not; a straight retry crosses the same limit at the same place.

How to fix: agent timed out when agent tried to query BigQuery metrics error timeo

The how-to phrasing for the same failure in BigQuery. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

BigQuery troubleshooting for this failure

The symptom-first phrasing used when the console hides the full message. Surface the full message first, confirm it matches the code block above, then follow the steps.

Compatibility: BigQuery at current versions, plus the platform API or console the query names; no extra tooling beyond a text editor and the source system access needed to verify counts.
