...ord, Mark just reported this to me under windows so it was a problem there too, but it does work under GCC 4.1. No idea which compiler is "correct", but that hardly matters... > Can't seem to forward define Database::Internal to make > Database::Internal a friend so just use LeafPostList directly > as that seems less bad than pulling in the whole of database.h > or making PostingIterator::internal public. Only problem with this patch is that it looks like it leaks the LeafPostList if an exception is thrown by one of the other methods (such as delete_document()). Actually,...

Going back to the "prioritizing aggregated DBs" thread from February 2020, I've got 390 Xapian shards for 130 public inboxes I want to search against(*). There's more on the horizon (we're expecting tens of thousands of public inboxes). After bumping RLIMIT_NOFILE and running ->add_database a bunch, the actual queries seem to be taking ~30s (not good :x). Now I'm

By way of introduction, I manage YottaDB (https://yottadb.com and https://gitlab.com/YottaDB). The core of YottaDB is a hierarchical key-value datastore (https://docs.yottadb.com/MultiLangProgGuide/cprogram.html and https://gitlab.com/YottaDB/DB/YDB). The code base is mature (in daily production use since 1986), and very performant, with strongly ACID transactions, and replication (to ensure
