Yes, indexing seems to be the big problem here...
I wonder if there's a way to move indexing out of "the zodb".
The main things I get from ZODB are simplicity of data storage (ie: just playing with python objects) and robustness of data.


For the first point, indexing is never simple ;-)
For the second, if indexes become corrupt, they can be rebuilt.

I wonder if there's something to be said for having a generic object indexing service that didn't use ZODB but used its own local indexes and re-indexed as needed or if the indexes are corrupt?

I've explored a SQLCatalog (all indexes are in SQL) implementation
developed for the ERP5 project a while back. Besides writing a hell of a
lot a SQL, the idea is promising.


if you didn't want to use sql, there is the zemantic route.

rdflib lets you interfaces a number of different backends(sql or not) and comes with a rich query api.
