+|`name`| e.g. `DynamoDB UpdateItem my_table`|  The span name should capture the operation name (as used by AWS for the action name) and the table name, if available. The format should be `DynamoDB <ActionName> <TableName>`. TableName MAY be omitted from the name for operations (`batchWriteItem`, `batchGetItem`, PartiQL-related methods like `executeStatement` etc.) that are acting on more than a single table. If `TableName` is not available, agents SHOULD also check the `TableArn` or `SourceTableArn` query params for a table name and extract the table name from the AWS ARN value.|
