every storage type has s3 kay key and "type" = "S3"

Thanks for the report! The reason every non-HDFS example uses "type" = "S3" and s3.access_key / s3.secret_key is that the FE StorageVaultType enum (fe/fe-core/.../catalog/StorageVault.java) only accepts two values — S3 or hdfs (case-insensitive). Doris talks to all object stores (S3, OSS, COS, OBS, BOS, MinIO, Azure Blob, GCS) through the S3-compatible API, and the actual cloud is selected by the separate provider property. The s3.* naming follows the same convention and is not literally about AWS S3.

This is engine-correct behavior, but the doc didn't make it obvious. PR #3748 adds a clarifying :::note right before the ### S3 Vault parameter table across all six pages (current/3.x/4.x EN + zh) explaining the type vs provider distinction. Closing once merged. cc @KassieZ
