public enum RequestOptions.Priority extends Enum<RequestOptions.Priority> implements ProtocolMessageEnum

The relative priority for requests. Note that priority isn't applicable for BeginTransaction.

The priority acts as a hint to the Cloud Spanner scheduler and doesn't guarantee priority or order of execution. For example:

• Some parts of a write operation always execute at PRIORITY_HIGH, regardless of the specified priority. This can cause you to see an increase in high priority workload even when executing a low priority request. This can also potentially cause a priority inversion where a lower priority request is fulfilled ahead of a higher priority request.
• If a transaction contains multiple operations with different priorities, Cloud Spanner doesn't guarantee to process the higher priority operations first. There might be other constraints to satisfy, such as the order of operations.

Name	Description
PRIORITY_HIGH	This specifies that the request is high priority. PRIORITY_HIGH = 3;
PRIORITY_HIGH_VALUE	This specifies that the request is high priority. PRIORITY_HIGH = 3;
PRIORITY_LOW	This specifies that the request is low priority. PRIORITY_LOW = 1;
PRIORITY_LOW_VALUE	This specifies that the request is low priority. PRIORITY_LOW = 1;
PRIORITY_MEDIUM	This specifies that the request is medium priority. PRIORITY_MEDIUM = 2;
PRIORITY_MEDIUM_VALUE	This specifies that the request is medium priority. PRIORITY_MEDIUM = 2;
PRIORITY_UNSPECIFIED	PRIORITY_UNSPECIFIED is equivalent to PRIORITY_HIGH. PRIORITY_UNSPECIFIED = 0;
