What is the impact of concurrency on transactions in databases?
Concurrency in databases allows multiple transactions to occur simultaneously, which can improve performance but also introduces challenges like data inconsistency.
Can you explain how concurrency control mechanisms work?
Concurrency control mechanisms, such as locking and timestamp ordering, ensure that transactions are executed in a way that maintains data integrity and consistency.
What are the common issues that arise from high concurrency?
Common issues include deadlocks, where two transactions wait on each other, and lost updates, where one transaction overwrites changes made by another.
How can I mitigate the risks associated with concurrency?
You can mitigate risks by implementing proper isolation levels, using optimistic concurrency control, and regularly monitoring transaction performance.
