Damien Elmes	2cd7885ec0	add begin/commit/rollback, and support creating collections ... all but one unit test is now passing	2020-03-20 21:15:23 +10:00
Damien Elmes	b876d97770	use (or)json for DB bridge ... Some initial testing with orjson indicates performance varies from slightly better than pysqlite to about 2x slower depending on the type of query. Performance could be improved by building the Python list in rspy instead of sending back json that needs to be decoded, but it may make more sense to rewrite the hotspots in Rust instead. More testing is required in any case.	2020-03-20 21:15:23 +10:00
Damien Elmes	04ca8ec038	initial work on DB handling in Rust ... committing the Protobuf implementation for posterity, but will replace it with json, as Protobuf measures about 6x slower for some workloads like 'select * from notes'	2020-03-20 21:15:23 +10:00
