Cradle / Submit Elasticsearch Schema
Submit Elasticsearch Schema
Submit an Elasticsearch schema definition to the cluster.
cradle elastic map cradle elastic map #!/bin/bash
# Submit Elasticsearch Schema
cradle elastic map import subprocess
# Submit Elasticsearch Schema
# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"cradle",
"elastic",
"map"
]
try:
print(f"Executing: {' '.join(cmd)}")
subprocess.run(cmd, check=True)
except subprocess.CalledProcessError as e:
print(f"Error: {e}")
except FileNotFoundError:
print("Error: cradle not found. Please install it first.")
if __name__ == "__main__":
run_command() When To Use
During a similar schema submission after upgrading Elasticsearch versions to ensure compatibility.
Pro Tip
Check for updates to the schema format in the latest version and apply undocumented optimization flags for performance.

Schema submitted successfully! Anatomy of Output
Understanding the result
PUT /my_index/_mapping HTTP Request This indicates the mapping operation for the specified index.
{"properties":{"field1":{"type":"text"},"field2":{"type":"keyword"}}} Request Body Defines the properties and their data types for the index.
HTTP/1.1 200 OK Response Status Confirms the successful schema submission.
Power User Variants
Optimized versions
cradle elastic map --update Updates the existing schema rather than replacing it.
cradle elastic map --dry-run Validates the schema submission without making changes.
Troubleshooting
Common pitfalls
404 Not Found: index_not_found_exception
Solution: Ensure the target index exists before submitting a schema.
400 Bad Request: validation_exception
Solution: Check the schema definition for compliance with Elasticsearch standards.
409 Conflict: version_conflict_engine_exception
Solution: Ensure the schema doesn't conflict with existing mappings.
