Neptune Loader Error and Feed Messages

The following messages are returned by the status endpoint of the Neptune Loader. For more information, see Get-Status API.

The following table contains loader feed code and description.

Error or Feed Code Description

LOAD_NOT_STARTED

Load has been recorded but not started.

LOAD_IN_PROGRESS

Indicates that loading is in progress and specifies the number of files currently being loaded.

When the loader parses a file, it creates one or more chunks to load in parallel. Because a single file can produce multiple chunks, the file count included with this message is usually less than the number of threads being used by the bulk load process.

LOAD_COMPLETED

Load has completed without any errors or errors within an acceptable threshold.

LOAD_CANCELLED_BY_USER

Load has been cancelled by user.

LOAD_CANCELLED_DUE_TO_ERRORS

Load has been cancelled by the system due to errors.

LOAD_UNEXPECTED_ERROR

Load failed with an unexpected error.

LOAD_FAILED

Load failed as a result of one or more errors.

LOAD_S3_READ_ERROR

Feed failed due to intermittent or transient Amazon S3 connectivity issues. If any of the feeds receive this error, overall load status is set to LOAD_FAILED.

LOAD_S3_ACCESS_DENIED_ERROR

Access was denied to the S3 bucket. If any of the feeds receive this error, overall load status is set to LOAD_FAILED.

LOAD_COMMITTED_W_WRITE_CONFLICTS

Loaded data committed with unresolved write conflicts.

The loader will try to resolve the write conflicts in separate transactions and update the feed status as the load progresses. If the final feed status is LOAD_COMMITTED_W_WRITE_CONFLICTS, then try resuming the load and it will likely succeed without write conflicts. A write conflict is not usually related to bad input data, but duplicates in data can increase the likelihood of write conflicts.

LOAD_DATA_DEADLOCK

Load was automatically rolled back due to deadlock.

LOAD_DATA_FAILED_DUE_TO_FEED_MODIFIED_OR_DELETED

Feed failed because file was deleted or updated after load start.

LOAD_FAILED_BECAUSE_DEPENDENCY_NOT_SATISFIED

The load request was not executed because its dependency check fails.

LOAD_IN_QUEUE

The load request has been queued up and is waiting to be executed.

LOAD_FAILED_INVALID_REQUEST

The load failed because the request was invalid (for example, the specified source/bucket may not exist, or the file format is invalid).
