Subject Change timer runtime
Date Mon, 02 Sep 2013 08:16:17 GMT
Hi all.

I have a problem regarding changing the timer period on the fly. My concrete
problem is that I have around 1.200.000 historic records I need to extract
at one time, and the database table is updated every 24 hours. Furthermore
I'm extracting from a Microsoft SQL database.

My preliminary tests have shown that I can't retrieve more than 3000 rows at
a time.

All this means that I would like to create a route that starts out by
extracting 3000 rows, at a time, as fast a possible. When all the 1.200.000
historic records have been extracted, the timer period should be changed to
only "fire" every 24 hours.

I have been looking into the throttler component, but I'm not sure that one
will work. The reason for this is that it will only be in a very short time,
that I want to poll as fast as possible, and after that I will only poll
every 24 hours for eternity. Furthermore, I can't figure out how the
throttler component know when to hold back. As I understand, the throttler
is controlled by how many exchanges that are going on right now, and
therefore only relates to the internal part of Camel. This means that the
throttler doesn't care about me only wanting data from a remote place every
24 hours.

Best regards

Lasse Vestergaard
