Could you please explain what exactly is "/*+ parallel */" in SQL, and how it is used? I'm curious to know how it can help in improving query performance and what are the considerations one should make before using it. Is it a common practice in SQL optimization, and are there any potential drawbacks or limitations to be aware of? Thank you in advance for your insights.

When it comes to performance optimization, parallelism is a powerful tool. By specifying "/*+ parallel 4 */" in a database query, you are instructing the optimizer to use parallel execution, but leaving the decision on the degree of parallelism up to the database. This approach can significantly improve query performance, especially for large datasets.
