PartitionEmbeddingIndexState

Progress of a partition’s re-index: after its embedding profile changes, every file is embedded again with the new model. The file counts are recounted each time the re-index moves forward, so files added or deleted while it runs are counted correctly.

Kind: an object, used in responses.

Fields

Every field is present in a response; empty ones are null.

Field	Type	Description
status	PartitionEmbeddingIndexStatus	Where the re-index is: Ready, Reindexing or Failed.
startedUtc	datetime | null	When the current re-index was requested (UTC).
preparedUtc	datetime | null	When the old index was cleared and every file lined up to be embedded again (UTC). The re-index cannot complete before this is set.
completedUtc	datetime | null	When the re-index finished successfully (UTC). Null while it is running or after it failed.
lastProgressUtc	datetime | null	When the counts last moved (UTC).
totalFiles	integer | null	Files in the partition at the last progress update. Null until the re-index is prepared.
completedFiles	integer | null	Files already embedded with the new profile at the last progress update.
unindexedFiles	integer | null	Files that could not be embedded with the new profile when the re-index was completed without them, because each had failed repeatedly. Null when none were left behind. They are retried automatically, so this is a count to show, not a permanent loss.
failureReason	string | null	A stable code for why the re-index failed, so you can show your own explanation: credentials-failed (every key failed, and falling back to Maitento’s is not allowed), no-credentials (no key for the new provider, and no consent to use Maitento’s) or walk-failed (preparing the re-index kept failing; send the profile again to retry). Null unless it failed.
previousProfile	PartitionEmbeddingProfile| null	The profile the partition had before this re-index. Null: the default.
