I have some questions regarding packed fields, and storing/serializing data. What i want to do essentially, is to store 4MB of data to a file.
The data i have comes as uint8_t (a byte) and i want to store these as efficiently as possible. I have been testing a variety of protobuf setups (four); repeated uint32_t datastruct = 1; repeated uint32_t datastruct = 1 [packed = true] with both variants assigned 1-to-1 and both variants bitshifted 4 values into a uint32_t. To my surprise the stored files are much larger than the original data. The best result i could achieve was 5.2MB for the 4MB data, which really isnt that good. Have i misunderstood something vital here? I do realize that protobuf adds information to the packets, but 25% increase is too much imho.
