The problem is then he has to create a storage engine plugin for something that isn't a storage engine. Everything isn't a hammer. What Barry needs is a simple plugin point that sends out a representation of the parsed query tree before the engine gets it. >> 2) The second plugin point is one some where after the 'Insert' or >> 'Update' >> statement has been processed but before the storage engine gets called. >> The > > So you need a before trigger on insert? Why not use what the replication > system has at that point? See above, and Barry's email. Because it is fired after the storage engine is notified, and, as Barry mentioned, he needs it before that... Barry, I think it is certainly possible to create such plugin points. The issue is going to be in the prioritization of that work. I can probably get to designing the plugin points (base plugin classes to put into /drizzled/plugin/ and the kernel callbacks to such plugins) in about a month or so. In the meantime, you can give it a try and we can work through things together? Sorry I can't be much more help...trying to get a ton completed on the replication side of things.. One final alternative might be to ask Primebase to sponsor a Google Summer of Code student who may not be accepted into the program this year? We had 48 applicants and have only 8 slots, so there will be a number who do not get accepted. Many of these students had excellent proposals and may be willing to take on the above work? Just an idea...trying to think outside the proverbial box. :) Cheers, -jay _______________________________________________ Mailing list: https://launchpad.net/~drizzle-discuss Post to : [email protected] Unsubscribe : https://launchpad.net/~drizzle-discuss More help : https://help.launchpad.net/ListHelp
