RE: bitmap indexes going wild

We have seen the same thing on AIX systems with 8.1.6. We did the same thing. Drop, load, rebuild.

Stéphane,
I have seen such behaviour with bit mapped index since 7.3.4.x. The index did not grow as much in 8.x versions. But it was still unacceptable. We drop all bit mapped indexes prior to data loads and rebuild them afterwards.
