Remarks

The work is bounded, idempotent, and restartable. A run processes at most a configured number of batches and then reports whether more remain; a batch commits its extractions together with the position it reached, so an interrupted run resumes at the next email rather than repeating or skipping one; and re-running over an email that already has its extraction simply overwrites it with the same reading of the same immutable bytes.

Nothing here reaches a mail server. Every byte it reads was fetched and stored by an earlier synchronization run, so a backfill cannot touch a remote \Seen flag however long it runs.

Constructors

StoredEmailExtractionBackfill(IStoredEmailExtractionBackfillStore, IEmailContentStore, IEmailMimeReader, OptimisticConcurrencyRetryPolicy, StoredEmailExtractionBackfillOptions)

Initializes a new extraction backfill.

Methods

RunAsync(CancellationToken)

Runs one bounded pass of the backfill.
