Anand Nadar updated RANGER-4841:
--------------------------------
Description:
When performing operations such as user-group membership creation or deletion
via the {{POST ugsync/groupusers}} endpoint, significant delays and occasional
exceptions occur due to high data volume in the {{x_group_users}} table.
Specifically, DELETE, UPDATE, and INSERT actions on user-group memberships lead
to the following error:

DELETE, UPDATE and INSERT of user-group memberships causes the above error.
*Resolution Steps:*
# *Separation of ID Retrieval Logic:* Move the retrieval logic for user IDs
that require modification (addition) outside the {{GroupUserMappingUpdator}}
thread. This separation helps streamline transactional management and reduces
contention on database locks during updates.
# *Eliminate Redundant Updates:* Modify the API behavior to avoid unnecessary
updates to {{{}x_group_users{}}}. The API should focus solely on creating or
deleting user-group memberships. Updating memberships that already exist serves
no practical purpose and contributes to transactional conflicts, as observed in
the error log.
By implementing these steps, you can mitigate the {{Lock wait timeout
exceeded}} errors and optimize the performance of user-group synchronization
operations within the application. This approach ensures smoother execution of
database transactions, particularly under high data load conditions in the
{{x_group_users}} table.

DELETE, UPDATE and INSERT of user-group memberships causes the above error.
*Resolution Steps:*
# *Separation of ID Retrieval Logic:* Move the retrieval logic for user IDs
that require modification (addition or deletion) outside the
{{GroupUserMappingUpdator}} thread. This separation helps streamline
transactional management and reduces contention on database locks during
updates.
# *Eliminate Redundant Updates:* Modify the API behavior to avoid unnecessary
updates to {{{}x_group_users{}}}. The API should focus solely on creating or
deleting user-group memberships. Updating memberships that already exist serves
no practical purpose and contributes to transactional conflicts, as observed in
the error log.
By implementing these steps, you can mitigate the {{Lock wait timeout
exceeded}} errors and optimize the performance of user-group synchronization
operations within the application. This approach ensures smoother execution of
database transactions, particularly under high data load conditions in the
{{x_group_users}} table.

> *Resolution Steps:*
> # *Separation of ID Retrieval Logic:* Move the retrieval logic for user IDs
> that require modification (addition) outside the {{GroupUserMappingUpdator}}
> thread. This separation helps streamline transactional management and reduces
> contention on database locks during updates.
> # *Eliminate Redundant Updates:* Modify the API behavior to avoid
> unnecessary updates to {{{}x_group_users{}}}. The API should focus solely on
> creating or deleting user-group memberships. Updating memberships that
> already exist serves no practical purpose and contributes to transactional
> conflicts, as observed in the error log.
> By implementing these steps, you can mitigate the {{Lock wait timeout
> exceeded}} errors and optimize the performance of user-group synchronization
> operations within the application. This approach ensures smoother execution
> of database transactions, particularly under high data load conditions in the
> {{x_group_users}} table.
