Class JobLeaseOwner

Namespace

MailFathom.Application.Jobs

Assembly

MailFathom.Application.dll

Names the attempt that holds a lease, so a later write can be refused when the lease has moved on.

Remarks

It identifies one attempt rather than one process. Completion, renewal, and release are all conditional on this value still matching the row, and a worker that lost its lease, finished late, and tried to write its result finds the row owned by the attempt that replaced it and writes nothing. A value that named only the process would let a reclaimed job be completed by the attempt whose lease had already expired.

The text is MailFathom's own — a generated identity for the attempt — and never anything from a message.

Fields

MaximumLength

The greatest length an owner may have, which bounds the column it is stored in.

Properties

Value

Gets the text a stored lease is compared against.

Methods

Returns a string that represents the current object.
