Hi forum, it’s been a while,

I would like some input from you brainics on the following;
I have huge textfile (GB) where each line starts timestamp.

timestamp0 data
timestamp1 data
...

So given a timestamp as input I need to locate the closest timestamp in the file and then parse line by line. Naturally this seek operation should be quick!

Well we know that this has been done a billion times before, however it hasn’t been done by me

I should be mentioned that the huge textfile, is produced during a recording session which I control - opening for a possibility to produce a secondary meta data file during the recording. (well to be fair there is actually already a meta data file containing some json (however no indexing)).

Surely there must exist a “by the book” solution here.

Thanks!
