Hi plesner, I don't think you are hitting the 2^63 limit. To do that you would have to read over your whole 10MB of data 1000 times per second for 232 years.
My guess is that there is indeed a bug in the Python library. Could you file a bug against pycapnp, and include a test case to show which code path you are hitting? -Kenton On Tue, Feb 14, 2017 at 1:26 AM, <[email protected]> wrote: > Over the weekend I migrated the android app I'm working on from using > protobufs to capnproto messages and it's been great -- I zip the data > anyway so it's not much larger and the infinite speedup when loading really > makes a difference for what I'm doing.
