When implementing indexing, what factors should be considered to mitigate the impact on database write performance?

When implementing indexing, factors to consider for mitigating the impact on write performance include selective indexing (indexing only the columns that are frequently queried), choosing an appropriate index maintenance strategy (e.g., periodic maintenance rather than immediate updates), and using index-only scans to reduce disk I/O during reads. Increasing the index size can have a negative impact on write performance, so it should be done judiciously.
