What is the difference between indexing and partitioning in MySQL?

Indexing is a technique to improve query performance by creating a data structure that allows for faster lookups. Partitioning, on the other hand, involves dividing a large table into smaller, more manageable pieces, which can improve performance and maintenance.

Can you explain how indexing works in more detail?

Sure! Indexing creates a data structure, like a B-tree, that allows the database to find rows quickly without scanning the entire table. It speeds up read operations significantly.

What are the benefits of partitioning a table?

Partitioning can enhance performance by allowing queries to scan only relevant partitions, reduce maintenance time, and improve data management.

Are there any downsides to using indexing or partitioning?

Yes, indexing can slow down write operations due to the overhead of maintaining the index. Partitioning can add complexity to queries and may require more careful design.
