Welcome to the RingCentral Community

I am writing a searchable indexing engine for calls from the call log. In setting up the database structure, I want to ensure I am using database fields that are long enough to support the data, but also short enough to be efficient if my app is processing millions of these records in a single search. I don't see any documentation for max lengths of the 4 key fields I am indexing (Name, Number, XNumber, and Location): https://developer.ringcentral.com/api-docs/latest/index.html#!#MessageStoreCallerInfo

Is there any documentation of the max length of these fields from RingCentral? If not, is there a recommended length to use?
