255 rows/page limit should be addressed

Informix has a rows/page limit of 255 rows/page.

Perhaps this was not a problem originally but over time we have seen new features:

  • larger page sizes (up to 16 kB against 2 kB or 4 kB previously, dependent on operating system).

  • compression option.

This is coupled with the problem of the system limit of 16,777,215 pages per table or table partition which is documented in the following RFEs:

To increase the maximum size of a table or also to increase system efficiency large page sizes can be used, however for many narrow tables the benefit is taken away by being unable to fill a page.

The Informix compression option is superb and achieves amazing size reductions but the benefits are often only fully realised for indices where the rows per page limit does not exist. For tables small page sizes must be used for the majority of tables on our system to avoid hitting this limit.

Overall I think the negative consequences of this are:

  • DBA time in working out, dealing with the problem, goes against the idea that Informix has a low support requirement.

  • Unable to benefit from the efficiencies of larger page sizes without wasted space.

  • Wasted space, inefficient use of storage.

    All of the infrastructure to increase the maximum rows per page are already built in. There is a # of rows field in the page header and the slot table grows backwards from the trailing checksum field so the only problem seems to be the hard limit in the code when appending a row to a page.
