Do database triggers slow down?
A trigger fires inside the transaction that modifies the data in the table. The triggers of this type will not slow down operations, however, will ensure data coupling and integrity. Every time I experienced “lags” when adding data to a table with a trigger, it was an example of such a “heavy” query.
Should I use Postgres triggers?
In PostgreSQL, if you want to take action on specific database events, such as INSERT, UPDATE, DELETE, or TRUNCATE, then trigger functionality can be useful as it will invoke the required function on defined events. Depending on the requirement we can create trigger BEFORE, AFTER or INSTEAD of the events/operation.
Why are DB triggers bad?
Triggers are a requirement for any complex data integrity rules. These cannot be enforced anywhere except the database or you will have data integrity problems. They are also the best place for auditing unless you don’t want to capture all changes to the database (which is the problem of auditing from the application).

What’s the difference between PHP 5 and 7.1?
The PHP Classes website contains extensive details about all of the changes made between PHP 5 and PHP 7.1. What exactly is good PHP performance? Performance and speed are not necessarily synonymous. Achieving optimal performance is often a balancing act that requires trade-offs between speed, accuracy, and scalability.
