tcl - Keep mysql connection open -

-

i'm making eggdrop tcl script write activity of several public irc channels database (over time 10 15 channels think). have 2 options how handle database connection in mind.

  1. an user says -> open mysql connection database -> insert information user said -> close connection
  2. start bot -> open mysql connection database -> insert information when there channel activity -> wait more information etc.

i think it's better use case 1, when there channel activity think opening , closing connection every time cause massive server load , slows things down drastically after while.

what's best way this?

if want keep connection open call

mysql::ping $dbhandle

from time time.

this can done this:

proc keepmysqlopen {dbhandle} {     mysql::ping $dbhandle     after 2000 [list keepmysqlopen $dbhandle] } ....     set dbh [mysql::open ...]     keepmysqlopen $dbh ...

an other option use mysql::ping before accessing db, should according mysqltcl manual reconnect if necessary. might best of both worlds (let connection time out if there not activity, keep open otherwise).
