Java updating large binary file

Tag : java , By : user179271

will be helpful for those in need Well I figured out a solution that doesnt require another copy of file. I simply take first offset to delete, jump to offset + its lenght, take a bounch of bytes lets say minimum (distance to next deleted object) and maximum 1k, paste it at the offset of the deleting entry and look for another one to delete, nto sure if i explained it in a proper way but well, asnwering your own question often leads to that kind of issue xD

Python multiprocessing: Reading a large file and updating an imported dictionary

Hope that helps I need to read a large file and update an imported dictionary accordingly, using multiprocessing Pool and Manager. Here is my code: , Try this code:
d = init_dictionary( ) # some your magic here

def f(line):
    data = line.split('\t')
    uid = data[0]
    tweet = data[2].decode('utf-8')

    if uid in d: 
        for n in d[uid].keys(): 
            if n in tweet: 
                 yield uid, n, 1 
                 yield uid, n, 0 

p = Pool(4)

with open('~/test_1k.txt') as source_file:
    for stat in p.map(f, source_file):
          uid, n, r = stat
          d[uid][n] += r

Unity: Reading and updating from large CSV file

This might help you With files that large, you should start looking for alternatives. Here's some ideas, but the best option depends on what specifically you're doing.
Can the component updating this CSV instead communicate directly with Unity3d? Using, e.g. a socket connection would avoid the need to save and read this information to and from the disk constantly. However, this depends on how this CSV data is being created, obviously Could you split the csv into smaller files? One for each timestamp, for instance? This way, there's less overhead to update the simulation at each step. Can you reduce the frequency of your updates? Is it essential to update every second? Or, can you only read from the CSV every, say, 10 seconds, load in all the data for the next 10 seconds (all timestamps in that range, for instance), store them in memory, and then for the next 10 seconds only use the info from memory to update instead of reading the file again? This will reduce your calls to the disk.
