( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Short answer: too many variables to tell. You should be ok, though. I've got a CMS that sometimes has to read two megabytes of xml and manages it without becoming unusable. It's not the right way for me to be doing it, but it just grew, and it still works ok. I suspect that it will be issues of data integrity or structure that make you shift, not capacity.

Anyway, if you use DBI and something like DBD::CSV to manage access to your flatfiles, then you'll have a ready-made layer of abstraction between the scripts and the data. in which case it kind of doesn't matter about the ceiling: if you seem to be reaching it, you can switch to something with more headroom just by changing a line or two in the top of the script (and getting the IT people to provide a bit of access to the databases. Not in that order.)

There are useful discussions of DBI and DBM around, if you want to look into that further.

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 How to display code and escape characters are good places to start.
