Review Comment:
Yes, we are updating it for all the APIs. It was discussed offline to not
keep separate versions for different APIs and instead go for an overall API
version upgrade.

> We have implemented create and rename recovery using client transaction IDs
> over the DFS endpoint ([HADOOP-19450] [ABFS] Rename/Create path idempotency
> client-level resolution - ASF JIRA). Since the backend changes were not fully
> rolled out, we initially implemented the changes with the flag disabled. With
> this update, we aim to enable the flag, which will start sending client
> transaction IDs. In case of a failure, we will attempt to recover from the
> failed state if possible. Here are the detailed steps and considerations for
> this process:
> 1. **Implementation Overview**: We introduced a mechanism for create and
> rename recovery via client transaction IDs to enhance reliability and data
> integrity over the DFS endpoint. This change was initially flagged as
> disabled due to incomplete backend rollouts.
> 2. **Current Update**: With the backend changes now in place, we are ready to
> enable the flag. This will activate the sending of client transaction IDs,
> allowing us to track and manage transactions more effectively.
> 3. **Failure Recovery**: The primary advantage of enabling this flag is the
> potential for recovery from failed states. If a transaction fails, we can use
> the client transaction ID to attempt a recovery, minimizing data loss and
> ensuring continuity.
> 4. **Next Steps**: We will proceed with enabling the flag and closely monitor
> the system's performance. Any issues or failures will be documented and
> addressed promptly to ensure a smooth transition.
