The number of types a index can handle

11149 · July 30, 2014, 5:18am

index -> database
type -> table (HERE)
doc -> row

I want to know is there a limit on the number of types in a index and how
many is too many ?

There is no limit in ES.

Each type uses a certain amount of heap for caching ids and the mapping.
You can create types / mappings until heap explodes. Each modification of a
mapping is propagated through the cluster, which is not a cheap operation.
You have to test by yourself if your design works.
