Module connect 

Connector adapters for datum-sql.

These adapters keep connector metadata outside Arrow row data. The per-batch envelope carries only source position and schema revision; time, watermarks, barriers, and checkpoint epochs belong to later control-envelope work.

Structs

BatchEnvelope

Side metadata for one emitted SQL batch.

EnvelopedBatch

A data batch paired with connector-side metadata.

Type Aliases

EnvelopedRecordBatch

Append-only Arrow batch with connector-side metadata.
