Leaving child out from inner results was quite obvious mistake. Now
paging works and queries are fast. Thank you!

But I think we can handle this by adding paging, so not a show stopper...

The builds end up in a maven repo:

I'm happy to try out the snapshot. Its just matter of ru

Hi Rob,
Im using this command to start db:

worth noting that some queries are simply hard for any query

I read that TDB is faster. What is the reason not to use TDB? Cant find
any comparison on SDB and TDB in that regard.

Cause of error might be the same as discussed earlier: inserts being

Hi,
what do you mean by masking? It should remove duplicates and it makes

Hi Andy,

Ok concatenating looks like the easiest solution for me. Is the update
rate limit related to speed only - would just adding some delay between
insertions solve the issue too?
