Failure to read a process-bound checkpoint timing page.

Variants

ProcessIdentityRequired

A nonzero sequence cursor omitted its process-generation identity.

ProcessIdentityUnavailable

A live local process identity could not be sampled without waiting.

ProcessIdentityMismatch

The supplied cursor belongs to a different process generation.

Fields

expected: LocalProcessAuthorityIdentity

Process identity supplied with the cursor.

actual: LocalProcessAuthorityIdentity

Live process identity observed before the read.

ProcessIdentityChanged

Process authority changed while the in-memory ledger was read.

Fields

before: LocalProcessAuthorityIdentity

Identity observed before the ledger read.

after: LocalProcessAuthorityIdentity

Identity observed after the ledger read.

LedgerProcessMismatch

The ledger’s immutable sequence domain contradicts current process authority.

Fields

expected: LocalProcessAuthorityIdentity

Live process identity sampled around the read.

actual: LocalProcessAuthorityIdentity

Process identity bound to the ledger’s sequence domain.

Snapshot(CheckpointBarrierTimingSnapshotError)

The bounded ledger snapshot itself failed.
