 14.5.5 Things We Need to Fix for `BDB'
 --------------------------------------
 
    * Opening many `BDB' tables at the same time may be quite slow. If
      you are going to use `BDB' tables, you should not have a very
      large table cache (for example, with a size larger than 256) and
      you should use the -no-auto-rehash option when you use the `mysql'
      client.
 
    * `SHOW TABLE STATUS' does not provide some information for `BDB'
      tables:
 
           mysql> SHOW TABLE STATUS LIKE 'bdbtest'\G
