TIL elastic doesn't have inferred schemas. I always assumed they did. :mindblown:

Lack of inferred/flexible schemas was the main reason we reluctantly spent nearly two years building our own datastore instead of using druid. It is absolutely fundamental to observability.
If o11y is about being able to "ask any question, understand any state, without shipping new code", then you need to eliminate any friction around accumulating richer detail.

You want to incentivize engineers to stuff in ANYTHING that might someday be useful, anytime, anywhere.
The last thing you want is for anyone to have to stop and think about managing schemas or migrations or updating clients to match the schema version or what the data type is, etc.

Same goes for indexes. Choosing in advance what people can efficiently search on? Not observability
