Hi,
untill today i used the mtree module to get some data from a remote DB and
load it into memory.
the table in the data base has 5 million rows. prefix is a number and
value is some string.
i moved to htable because i need the prefix exact match and not longest....
now, after 5-10 sec, i get the following error (that i never got in mtree)
- "lost connection to mysql during query" and kamailio does not start.
any ideas how to solve it?
cheers,
Uri

iirc, htable does a sort with the query retrieving the data, in order to
cope with "array" structures -- this may take a while in the mysql
server, do you get any logs in the log file of mysql daemon?
Maybe an option to disable this sorting, for people not needing the
"array" functionality would be good to speed up a bit.
Cheers,
Daniel

Hey,
I didn't get any logs from the mysqld.
An option to disable this sorting will be great.
Thanks,
Uri
