Hi [~vlovich],
could you please indicate what language you are talking about? Simply set the
component at the ticket, that avoids a lot of possible confusion. If you also
have a short example at hand explaining the issue, please add it.
Thanks!

> _isset entries shouldn't be generated for non-optional fields

> Key: THRIFT-2473
> URL: https://issues.apache.org/jira/browse/THRIFT-2473
> Project: Thrift
> Issue Type: Bug
> Reporter: Vitali Lovich
>
> There's quite a bit of memory overhead (4 bytes per field) that's wasted on
> every single type. The __isset field is unused by the thrift type for fields
> not annotated optional.
> Additionally, it causes confusion in program code since people never know
> whether or not the __isset struct can be checked for a particular field or
> not (e.g. for non-optional fields it would never get set normally unless you
> deserialized it).
