I'm trivially inserting n to a db throug a grpc server
When I use the non streamed version I have to call the stub n times and
got n calls to my observer , whereas when I use the stream I just call the
stub once and call the request observer n times for onNext(E).
Aparently the streamed version should be faster but for 2000 records 12
seconds/non stream and 2 min abd 31 seconds /streamed version for 5
records 1min 28sec /non stream 64min 47seconds
>From the server side you notice that the records are inserted not in order
showing off an asyncronous behaviour in the non streamed case, and
perfectly ordered in the streamed case.
Is that the expected behaviour, so calls to stream are syncronically
treated, and the non streamed asyncronouslly (at server side)?
The code below ilustrates the issue but it's only a draft
Thank you
service kgrpcServer{
rpc addE1(E) returns(newId){}
rpc addE2(stream E) returns(newId){}
}
val e =E.newBuilder()
val limit=51000
val cnt=CountDownLatch(1) //=1 for streamed version =limit for non
streamed version
SX1.cnt=cnt <--The stream observer with a lach on it
for(n in 0..limit-1) {
print("\r"+n)
e.t1 = "second"
e.t2 = n.toString()
EXP.addE2(e.build()) <--EXP a facade to make the rpccalls
either streamed non streamed, in the server side a database register will be
created for each call
Thread.sleep(1)
}
cnt.await()
EXP.end() <--- Close conection
println("All done")
