This PR adds an hourly logging mechanism for the database, which will show queries executed, most common query patterns and potential N+1 queries. It also adds the ability to log an analysis on the spot using
getAnalysis(). The logger is very simple and file-based.Here is an up to date analysis using the analyzer:
typeorm-analysis.log
I've decided to log the full stack trace when discovering potential N+1 queries because sometimes the actual file where the query is executed is at the top, sometimes at the bottom. It also logs the full query minus parameters in "Top 5 Query Patterns", so it's GDPR-compatible.
There are some obvious optimisations in the diff callbacks, some of which I've already implemented.
