ExStorageService.Metadata (ex_storage_service v0.6.2)

Copy Markdown View Source

Metadata operations backed by Concord key-value store.

Legacy keys are namespaced:

  • Buckets: "bucket:{name}"
  • Objects: "obj:{bucket}:{key}"

Object reads prefer the atomic v2 schema and fall back to these v1 records.
