faucet-common-delta

Shared configuration and helpers for the faucet-stream Delta Lake connectors — faucet-source-delta and faucet-sink-delta. Built on the Rust deltalake crate (delta-rs).

Provides:

• DeltaCredentials — object-store credentials (default chain / aws / azure / gcp), each mapping to the storage_options keys delta-rs expects.
• DeltaConnection — the shared table_uri / credentials / storage_options block (flattened into both connector configs) plus the open-table, time-travel, storage-option, and handler-registration helpers.
• convert — Arrow ⇆ JSON conversion (record_batch_to_json, infer_arrow_schema) reused by the source (read) and sink (write).

Cloud object-store backends are opt-in cargo features (s3, azure, gcs) that forward to the matching delta-rs feature; the default build supports the local filesystem only.

Connector authors normally depend on faucet-source-delta / faucet-sink-delta, which re-export the types they need from here.
