I'm wondering about the circumstances under which I should avoid using indexing. Is it related to certain database operations, data types, or performance considerations? I'd like to understand when it's not beneficial or could even be counterproductive.

Indexes are created primarily to enhance the efficiency of a database.

Columns that contain a large number of null values are also not suitable for indexing. Indexes work best when the values in the column are relatively unique, as this allows the database to quickly locate the desired rows. When a column has many null values, the effectiveness of the index is reduced.

One such scenario is when dealing with small tables. In these cases, the overhead of maintaining an index may outweigh the benefits it provides in query performance.

Another situation where indexes should be avoided is on tables that undergo frequent large batch updates or inserts. This is because indexes need to be updated whenever the underlying data changes, which can significantly slow down these operations.
