Subject Compression.Algorithm extensibility?
Date Mon, 28 Nov 2011 16:26:18 GMT
Hi folks-

In Compression.java there is this comment…


  /**

   * Compression algorithms. The ordinal of these cannot change or else you

   * risk breaking all existing HFiles out there.  Even the ones that are

   * not compressed! (They use the NONE algorithm)

   */

  public static enum Algorithm {

… which makes the prospect of adding new instances slightly terrifying.  Has anybody considered
changing the constructor to supply an ordinal value, and that way if anybody adds a custom
one they could supply a value like 9999999 or something hopefully never used by HBase?
