Cause (Documented platform behavior): Circuit breakers protect the node from OOM; small heaps plus large bulk requests/vectors trip them.

Problem details
- Observed symptom
- Requests rejected with 429; retries sometimes succeed; cluster may look healthy.
- Context
- Product: Elasticsearch Component: parent circuit breaker Operation: Bulk-indexing embeddings/large documents or running heavy aggregations against a dev/single-node container with a tiny JVM heap Affected versions: unknown Environment: unknown HTTP status: 429 Packages: elasticsearch current (main/docs) Trigger: Estimated heap usage would exceed the parent breaker (95% of JVM heap by default).

Proposed fix: [Elasticsearch with small heap (Docker ES_JAVA_OPTS=-Xmx512m, CI)] 429 circuit_breaking_exception '[parent] Data too large, data for [<http_request>] would be [...], which is larger than
Recommended action: Reduce request size (smaller bulk batches, fewer concurrent requests), give the node more heap (ES_JAVA_OPTS / container memory), and check _cat/nodes heap usage; retry with backoff on 429.
Option: Smaller batches and more heap [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. Bulk in chunks (e.g. a few MB per request)
2. docker: -e ES_JAVA_OPTS='-Xms2g -Xmx2g' with enough container memory
3. GET _cat/nodes?v=true&h=name,heap*
Expected: Command proceeds without the error.
Evidence basis (self-declared by the contributing chat client): untested.
