startTime
|
The time when the work item attempt became a straggler. Uses RFC 3339, where generated output will always be Z-normalized and uses 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: |
causes
|
The straggler causes, keyed by the string representation of the StragglerCause enum and contains specialized debugging information for each straggler cause. |
StragglerDebuggingInfo
Information useful for debugging a straggler. Each type will provide specialized debugging information relevant for a particular cause. The StragglerDebuggingInfo will be 1:1 mapping to the StragglerCause enum.

The age of the hot key measured from when it was first detected. A duration in seconds with up to nine fractional digits, ending with ' |
key
|
A detected hot key that is causing limited parallelism. This field will be populated only if the following flag is set to true: "--enableHotKeyLogging". |
keyTruncated
|
If true, then the above key is truncated and cannot be deserialized. This occurs if the key above is populated and the key size is >5MB. |
