• Run-length encoding (part 2)

  
  Daniel Lemire's blog — Authority: 113

• Run-length encoding (part I)

  
  Daniel Lemire's blog — Authority: 113
  Run-length encoding (RLE) is probably the most important and fundamental string compression technique. Countless multimedia formats and protocols use one form or RLE compression or another. RLE is also deceptively simple. It represents repeated values as a counter and a character. Thus, the string AAABBBBBZWWK ...

C-store —and presumably Vertica—is using similar compression techniques as well as simple run-length encoding ...

  Daniel Lemire's blog — Authority: 113
  Morteza Zaker sent me pointer to their work comparing bitmap indexes and B-trees in the Oracle database. They examine the folklore surrounding bitmap indexes—which are often thought to be mostly useful over low cardinality columns (columns having few distinct values, such as gender ).
