Lesson Learned #341: Index Disabled vs Performance Issues
Introduction
Lesson Learned #341 is an article that discusses the indexing process and the implications of disabling indexes on performance issues. It explains the importance of indexes and their impact on query performance, as well as how disabling indexes can affect the performance of queries.

What is Indexing?
Indexing is a process of organizing data in a database to make it easier to find and retrieve information. It creates an index, which is a data structure that stores the values of one or more columns in a table. Indexes help speed up the query process by allowing the database to quickly find the records it needs.

Why is Indexing Important?
Indexing is important because it can significantly improve query performance. Indexes allow the database to quickly locate the records it needs, which reduces the amount of time it takes for a query to execute. Without indexes, the database would have to search through all of the records in the table, which can take a long time.

What is the Impact of Disabling Indexes?
Disabling indexes can have a significant impact on query performance. If a query requires a large number of records to be retrieved, then disabling an index can cause the query to take much longer to execute. Furthermore, it can cause the query to take up more resources, such as memory and CPU, which can lead to further performance issues.

How Can We Avoid Performance Issues?
There are several ways to avoid performance issues when disabling indexes. First, it’s important to understand the impact of disabling indexes on query performance. Second, it’s important to understand the types of queries that benefit from indexing and which ones do not. Third, it’s important to test any changes to indexes before they are applied to production systems. Finally, it’s important to use the appropriate types of indexes for the types of queries being executed.
