[go-nuts] Re: Completeness of Golang drivers for open-source and enterprise databases.

Hello, The usql project (https://github.com/knq/usql) lists many SQL drivers, including some of the ones you are after. It seems that there is no DB2 driver and the current Sybase one is Windows only though. HTH Le jeudi 8 juin 2017 17:38:25 UTC+2, hari.e...@gmail.com a écrit : > > Hi All, > >

Are you exhausting the local TCP sockets? Some (50k?) in a wait state? Try using a few IP addresses on the test box. Increase /proc/sys/net/core/somaxconn to a larger value, if you have a 20 millisecond pause at 28kreqs/sec then thats 500 ish connections so 1024 may not be enough. -- You rece

Hi All, I get time on and off to do a bit of Go… i could be classified as a tinkerer at a very junior level (although i have been programming for a long time; i just haven't had enough hands on experience with Go to really get the hang of libraries and what "good architecture" in Go would look like

Re: [go-nuts] golang thrift server 28k/s request client many dial tcp timeout ,why??

Hi! One thing you should check is the amount of TCP sessions you are starting from one host. Since a TCP session is identified by the IP/Port in both ends, and you communicate where some of those numbers stay the same, you are probably limited to no more than 64000 ports at most (or such). If you

Hey James, Could you show the docker run command, which you invoke to enter a container? I use docker to build my application as well, so I just do `docker container run --rm -ti --volume $PWD:/gocode/src/app --workdir /gocode/src/app go build`. Doing so with container reusage or not, I haven

If you start chasing the code from a NewClient method, something like https://godoc.org/cloud.google.com/go/bigquery#NewClient, you will end up eventually at golang.org/x/oauth2/google. Reading the doc and code for DefaultCredentials and FindDefaultCredentials may answer all your questions: http

I meant the fully open connections waiting for application handling so the listen queue (somaxconn). On the client and server I'd check you aren't exhausting any of the more obvious limits, so ports/listen queues. Adding more virtual IPs is easy way to test the ports. Listen queues should show

Maybe your client's local ports is used out. threre are only about 65000 ports you can use to make a connection from a client to server per IP. You can check output of netstat to confirm that. On Sunday, June 11, 2017 at 9:48:30 AM UTC+8, 刘桂祥 wrote: > > //question > > I write a simple g
