title: What is the best nosql database to store files contain only integer lists
body: <p>I have over 60000 files ready to be stored in a nosql database. Each of them contains a certain number of lines, every line has integers with quite different scales. The later queries will find lines according to the line index, for example, look for the lists of line 2, 3, 5. I am quite new in nosql area, I don't know which nosql database would be the best to do it? Since I read that, Redis uses Key-value, while mongodb might good for json files. However, if the json file has a structure like <code>{key: &quot;1&quot;, value: &quot;12,24,57,865,567,4214314,436346,235,2341,2431,240978,324555&quot;}</code>, for me it seems to be the same as the concept of Redis.</p>
  <p>Furthermore, I will read the data in C, for memory allocating, I need to indicate the number of integers in a line as well. Would it be good if the structure looks like this: <code>{key: &quot;1&quot;, value: &quot;12,24,57,865,567,4214314,436346,235,2341,2431,240978,324555&quot;, num:&quot;12&quot;}</code>?</p>
