2 years ago The root problem here is that you cannot set the client threads per version after you open your database, it must be done before. The fact that this triggers an assertion rather than a friendlier error is a bug, and we have an existing issue for this:

ExternalClientLibrary means that libfdb_c? I also can't create multi network threads per second..

2 years ago @sfc-gh-ajbeamon hello
func getFdbConnection() fdb.Database { fdb.MustAPIVersion(620) op:=fdb.NetworkOptions{} err2 := op.SetExternalClientLibrary("/root/libfdb_c.so") fmt.Println(err2) err:= op.SetClientThreadsPerVersion(40) fmt.Println(err) db := fdb.MustOpenDatabase("/apps/dbdat/foundationdb/fdb.cluster") return db
}
I use this method to create multi network threads . no errors but only 3 threads
[root@localhost ~]# netstat -lnap | grep fdb | wc -l 10
[root@localhost ~]# netstat -lnap | grep fdb | wc -l 13
func main() { // Different API versions may expose different runtime behaviors. fdb.MustAPIVersion(610) // Open the default database from the system cluster db := fdb.MustOpenDatabase("/etc/foundationdb/fdb.cluster") op:=fdb.NetworkOptions{} //op.SetExternalClientLibrary("false") //op.SetDisableMultiVersionClientApi() //print(err) op.SetClientThreadsPerVersion(10) fmt.Println(db) }
