QUESTION
I followed the instructions at Structured Streaming + Kafka and built a program that receives data streams sent from kafka as input, when I receive the data stream I want to pass it to SparkSession variable to do some query work with Spark SQL, so I extend the ForeachWriter class again as follows:

You wouldn't use a ForEachWriter for that
QUESTION
I am trying to create a single TLS connection from a client to a server. Inside this tunnel, I would like to have two different types of streams: HTTPS traffic that I want the server to forward to a specific API server, and OpenVPN traffic(which is a combination of TLS and a TCP data stream). I am looking into WebSocket to do so, but can't find information on how to forward the stream to the correct destination (OpenVPN vs HTTPS API server) once it reaches my server. Is WebSocket a good solution for this? Is stunnel a better option? Are there existing solutions that offer this functionality?
...ANSWER
Answered 2021-Jun-14 at 06:54I've ended up solving this using SSLH and ghostunnel: on the client, I have started a ghostunnel listening on 127.0.0.1:8443 and forwarding the TLS-wrapped traffic towards a ghostunnel server I have in the cloud (listening on 443). I have directed my OpenVPN client to connect to 127.0.0.1:8443. I have also directed my HTTPS client to connect to 127.0.0.1:8443. On the server side, the traffic coming out of the ghostunnel server is funnelled into an SSLH server which in turn has two rules: forward TLS traffic to my webserver, and OpenVPN towards my OpenVPN server. The solution works great!

I've written a Pi Hardware Interface Server (phis) that uses http protocol to control the hardware connected to my Raspberry Pi (relays, analog measurements, etc). It processes simple requests and responds with plain text. It has been working flawlessly for years and I have written extensive browser-based interfaces to the system. Here's the basic structure:

I had forgotten to close the connected and listening sockets in the forked child, which were inherited by the spawned daemon and stayed open as long as it runs. Here's the code I'm using to spawn a process that will be left running (daemonized):

QUESTION
I am new into RxJava and I was under the impression that for each event each subscriber is being notified. So if we have N subscribers and a stream of X events the onNext
for each of the N subscribers would be called. But when I run the following code:
ANSWER
Answered 2021-Jun-13 at 08:05RxJava sequences are synchronous by default thus the subscribe call above will run your emission code right there. To achieve the interleaving, you need a way to tell the source when both consumers are ready to receive. This can be done several ways:
QUESTION
In my project, I'd like to make a simple user management program with MongoDB.
So I built a local server using Express of NodeJS and connected it to MongoDB.
After that, a schema called User was declared in Mongoose, and I made and tested a rest api that simply inserts data.
However, as a second attempt, duplicate key error collection occurred when testing with different uid values. (A first attempt was successful)
Can you tell me what's wrong with my design?
...ANSWER
Answered 2021-Jun-13 at 03:51In your userSchema you have defined uid as unique and when you are calling your /test endpoint you are always passing the same uid which is not unique, instead of that use uuid for the uid field.
QUESTION
Note: I'm new to network and dpdk, so there might be some misunderstanding in fundamental concepts...
I want to run 2 instances of dpdk-testpmd
on the same host to send and receive traffic over separate NIC.
Configuration:
NIC:
- PMD: MLX5
- version: 5.0-1.0.0.0
- firmware-version: 16.26.1040 (MT_0000000011)
- NUMA-Socket: same
- PCIe: 0000:3b:00.0, 0000:3b:00.1
Update
- DPDK Version: 20.11.1
- Hugepage Total: 32768
- Hugepage Free: 32768

...ANSWER
Answered 2021-Jun-13 at 05:04Note: I highly recommend reading about dpdk testpmd as it covered all your questions in detail. As per the StackOverflow guideline multiple sub-questions make answering difficult. Please use well-formatted and formed question for better reach and answers.
@Alexcured since you have mentioned you know how to run 2 separate instances of dpdk-testpmd
. I will only recommend heavily reading up on dpdk-testpmd URL which has answers to most of your questions too.
The assumption is made, both the PCIe NIC are working properly and interconnect between 2 are tested with either arping or ping (Kernel Driver). After binding both PCIe devices to DPDK supported drivers, one should use options for DPDK 20.11.1 such as
- use file-prefix option as unique names
- set socket-memory to fetch memory from the desired NUMA-SOCKET
- set socket-limit to prevent ballooning of huge page mmap
- use w|b option to whitelist|blacklist PCIe devices (0000:3b:00.0 and 0000:3b:00.1)
- Since it is separate physical devices ensure there physical cable connection between 2 PCIe ports.

...ANSWER
Answered 2021-Apr-22 at 20:32I have had the same issue. This is what I did:
- I deleted the
migrations
folder as well as thedist
folder - I ran
npx mikro-orm migration:create --initial
After that, I restarted yarn watch
and yarn dev
and it worked for me.
Notice the --initial
flag. I would recommend to check the official documentation. The migrations table is used to keep track of already executed migrations. When you only run npx mikro-orm migration:create
, the table will not be created and therefore MikroORM is unable to check if the migration for the Post entity has already been performed (which includes creating the respective table on the database).
Ben does not use the --initial
flag in his tutorial, he might have already ran it prior to the tutorial.
