Documentation

faucet-source-azure-blob

Azure Blob Storage / ADLS Gen2 source connector for the faucet-stream ecosystem.

Lists and reads objects from an Azure blob container (or ADLS Gen2 filesystem) and emits them as JSON records. Built on object_store's Azure backend, so both classic Blob and ADLS Gen2 hierarchical namespaces are supported through one code path.

Config

Connection fields come from faucet-common-azure and are set at the top level:

Field Type Notes
container string Required. Blob container / ADLS filesystem.
account string Storage-account name (optional with a connection string / emulator).
auth { type, config } account_key / sas_token / connection_string / managed_identity / service_principal / default.
endpoint string Custom blob endpoint (emulator / sovereign cloud).
allow_http bool Permit plaintext HTTP (Azurite).
use_emulator bool Target the Azurite emulator.

Source-specific fields:

Field Type Default Notes
prefix string Object-name prefix filter. Ignored when object_keys is set.
object_keys list Explicit object names; skips listing.
file_format enum json_lines json_lines / json_array / raw_text.
max_objects int Hard cap on objects read.
concurrency int 10 Max concurrent object reads.
batch_size int 1000 Records per StreamPage; 0 = one page per object.
compression enum auto auto / gzip / zstd (requires the compression feature).

File formats

  • json_lines — one JSON record per line; streamed line-by-line (bounded memory).
  • json_array — the whole object is a JSON array; buffered then chunked.
  • raw_text — each object becomes one record { "key", "content" }.

Example

pipeline:
  source:
    type: azure-blob
    config:
      container: raw
      account: mystorageacct
      auth: { type: account_key, config: { account_key: "${env:AZURE_KEY}" } }
      prefix: events/2026/
      file_format: json_lines
