What are common transaction isolation issues in databases?
Common transaction isolation issues include dirty reads, non-repeatable reads, and phantom reads.
Can you explain what a dirty read is?
A dirty read occurs when a transaction reads data that has been modified by another transaction but not yet committed.
How can I prevent dirty reads?
You can prevent dirty reads by using a higher isolation level, such as Read Committed or Serializable.
What are the trade-offs of using higher isolation levels?
Higher isolation levels can reduce concurrency and increase the likelihood of deadlocks, impacting performance.
