@Luandro Pàtwy db2 is just a database so in theory it should support bamboo as well. We didn't want to tackle bamboo in the first part because you still need to support the old format unless you go total greenfield, which for some applications might be a good idea, but was not our goal. That messages are stored in bipf is just an internal representation to make queries faster. I like bamboo very much and would love to use that as a feed format, meta feeds has a way to encode metadata about feeds including their format type.
