[storm-user] [Storm-Newbie] Race condition in Event Processing -How Storm can handle it

I have system which process events from a website ,analyzes the patterns
and stores it in database.

The database records are keyed with account_number. When multiple events
related to the account happens on web, the events try to update the (same)
record in the database ( the one related to the account). This results in
conflicts while updating.

I use optimistic locking. And its very hard to resolve conflicts.

Is there a way that storm can solve this problem.
I'm a newbie.
