 Random notes around the seektable, this is something I wanted for 0.28 but
 I'm not getting it ready and tested by tomorrow, so it has to wait until
 after the branch point of fixes/0.28.
 * spread recordedid around and have it replace chanid+starttime in the
 tables (includes some work on access functions / Service API, so they can
 still work with chanid+starttime)
 * work out the defaults that we have to override to get similar results
 across various versions of MySQL (https://dev.mysql.com/doc/refman/5.6/en
 /innodb-multiple-tablespaces.html file-per-table vs. all tables in one
 file changed in 5.6.6)
 * switch the small tables to InnoDB
 * enable referential integrity and fix all consistency bugs lurking around
 * switch the big tables (seek table) to InnoDB, choosing the primary key
 to optimize the data locality
 * reorder columns in tables / indexes (for data locality)
 * decide if the should mix the storage location of tables (e.g. all small
 ones into the system tablespace and the big ones into their own files)

 If someone has a (partial) implementation in their private repo, feel free
 to just grab this tracking ticket.
