Index Value Pair addresses compression on databases with larger block sizes, where the blocks are highly sparse. This compression algorithm is not selectable but is automatically used whenever appropriate by the database. The user must still choose between the compression types None, bitmap, RLE, and zlib through Administration Services.
Table 155 lists the available compression types the user can choose and the compression types that Essbase evaluates and then applies.
For example, if the user selects RLE, Essbase reviews each block and evaluates the following compression types for highest compression: RLE, bitmap, or Index Value Pair. If the user chooses zlib, zlib is the only compression type applied.
