What are the best practices for using STM in Haskell?
When using STM in Haskell, it's important to keep transactions small and focused. This helps to minimize contention.
Can you explain why small transactions are better?
Small transactions reduce the likelihood of deadlocks and make it easier for the STM system to manage memory efficiently.
What about error handling in STM?
In STM, you can use the retry
function to handle errors gracefully. It allows you to wait for a condition to be met before retrying the transaction.
Are there any performance tips for STM?
Yes, avoid excessive use of retry
and try to minimize the number of retries by structuring your transactions effectively.
