¶
keydbr is deprecated. Use robaho/leveldbr which is stable and uses an api based on Google's LevelDB.
About
Remote access to keydb database. Uses Google protobufs and gRPC.
Notes
There is a single gRPC stream per open database, upon which all requests are multiplexed. The stream is shared but requests are completed synchronously (since the server processes an inbound message synchronously) but this may change in the future to allow overlapping requests - that is, asynchronous handling by the server. For best performance, multiple connections should be made to the server, rather than sharing a database connection.
To Use
go run cmd/server
There is a sample command line client in cmd/client which uses the client API.
Performance
Using the same 'performance' test as keydb, but using the remote layer:
insert time 1000000 records = 3080 ms, usec per op 3.08019 close time 1700 ms scan time 2129 ms, usec per op 2.129979 scan time 50% 1468 ms, usec per op 2.93625 random access time 83.98727 us per get close time 1000 ms scan time 1963 ms, usec per op 1.963984 scan time 50% 930 ms, usec per op 1.861844 random access time 82.95168 us per get
TODOs
Implement "read ahead" for more efficient lookup over the network
