I feel this would bring in confusion to customers, mainly because transaction tags are supported in read-write transactions by using Options.tag. Customers might try using this Options.transactionTag for read-write and will not work.

Should we rename this to be more specific to PDML or is this somehow restricted to be used only for pdml transaction?

The official documentation states that transaction tags not supported for read-only transactions and are supported for read-write, but there’s no mention of partitioned DML transactions.
can you please verify if transaction tags are indeed supported for pdml txn?

Closing this because sending transactionTag in partitionDML is no-op |
