 Q:

Most efficient way to store a large number of key-value pairs of integers, separated by a delimiter, in a file

I have a system where two programs are concurrently reading and writing a file containing a large number of pairs of unsigned integers. The key can have a value [0,2^16) and the value can have a value [0,2^32). I am currently storing these integers in the file as characters, where each pair is on its own line, the key and value are separated by a single whitespace, and all values have 10 characters. 
The reason for the 10 characters is two-fold: 1. the largest unsigned integer, interpreted as characters, is 10 characters long, and 2. I am using mmap to map the file into both programs' memory, using the MAP_SHARED flag. When the program that writes to the file is first run, it will linearly scan the file and construct a hash map mapping the keys to pointers to the values. When the writer wants to put a new key-value pair into the file, it will search for the key in the hash map, and if that key exists, it will overwrite the value stored in the address associated with that key. I ensure that all values are stored as 10 characters in the file, where smaller values are padded on the right with whitespaces, so that the
