core.cache.debug.analyze_cache_queries(report: Literal['summary', 'redundant', 'all'] = 'summary') → collections.abc.Iterator[None]

Analyzes the redis commands executed during its context. Mirrors onegov.core.orm.debug.analyze_sql_queries(). There are three levels of information (report argument):

• ‘summary’ (only show the number of commands)

• ‘redundant’ (show summary and the keys hit more than once)

• ‘all’ (show summary and every command)

Unlike hooking our RedisCacheRegion, this counts the actual commands sent to redis, so cache layers that avoid a round-trip (e.g. the request/schema caches in front of orm_cached()) don’t inflate the numbers. Only two methods need hooking regardless of how the dogpile API evolves.

Use this with a with-statement:

with analyze_cache_queries():
    ...  # <- analyzes all redis commands that happen inside here
