Just a reminder, you were the first one suggesting that the OP needs more RAM, see Re: efficient perl code to count, rank

Anything can be done with Perl, but search and sort operations requiring Perl to keep all data in memory are usually easier solved (read out-of-the-box) with a DB.

Otherwise they require re-implementing sophisticated algorithms to manually "swap" RAM and Disk structures, which doesn't qualify as out-of-the-box for me.

NB: But IF the OP really needs such operations is still unclear!

We are still speculating what exactly he wanted to be ranked/sorted. (like demonstrated, sorting 14m entries is still feasible in RAM with Perl under 2min, but how does it scale with larger data?)

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
