A guide to Exasol’s Cloud Storage Extension for reading and writing structured files in object storage. Object storage is remote file storage such as Amazon S3, Azure Blob Storage, or Google Cloud Storage.

In plain words
What is it for?
Use it to import or export Parquet, Avro, ORC, or Delta files through the extension, including files stored in supported cloud or remote storage systems.
Why use it?
It helps choose and configure the extension workflow when native Exasol file import or export is not the appropriate route.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

exasol-cloud-storage-extension scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Exasol Cloud Storage Extension Skill

Trigger when the user mentions Cloud Storage Extension, FROM SCRIPT CLOUD_STORAGE_EXTENSION, INTO SCRIPT CLOUD_STORAGE_EXTENSION, CLOUD_STORAGE_EXTENSION.IMPORT_PATH, CLOUD_STORAGE_EXTENSION.EXPORT_PATH, Avro/ORC/Delta object-storage import, extension-based object-storage loading, extension-based Parquet reader, Avro through Cloud Storage Extension, ORC through Cloud Storage Extension, Delta through Cloud Storage Extension, extension-based Parquet export, or extension-based file reader.

Routing Algorithm

  1. Object storage and file-reader extension workflows
    • Trigger phrases: Cloud Storage Extension, FROM SCRIPT CLOUD_STORAGE_EXTENSION, INTO SCRIPT CLOUD_STORAGE_EXTENSION, CLOUD_STORAGE_EXTENSION.IMPORT_PATH, CLOUD_STORAGE_EXTENSION.EXPORT_PATH, Avro from object storage, ORC from object storage, Delta from object storage, ORC from S3, Avro from S3, Delta from S3, extension-based object-storage loading, extension-based Parquet reader, ORC through Cloud Storage Extension, Avro through Cloud Storage Extension, Delta through Cloud Storage Extension, extension-based Parquet export
    • Load: references/cloud-storage-extension.md

Notes

  • Use this skill when the user needs the Cloud Storage Extension UDF path rather than direct native IMPORT or EXPORT.
  • Use exasol-import for direct local-file and native SQL import behavior.
  • Use exasol-export for direct native SQL export behavior and local exapump export.
  • Use exasol-bucketfs when the user needs to upload, list, or remove the extension JAR in BucketFS.
  • Use exasol-document-virtual-schemas for federated read-only access to object or file storage.
  • Use exasol-extension-catalog only when the user is still comparing federation, copy, connector, or extension families.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
