kandi X-RAY | cp-demo Summary

cp-demo is a Shell library typically used in Data Processing, Stream Processing, Kafka applications. cp-demo has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

The use case is a Kafka event streaming application for real-time edits to real Wikipedia pages. Wikimedia's EventStreams publishes a continuous stream of real-time edits happening to real wiki pages. Using Kafka Connect, a Kafka source connector kafka-connect-sse streams raw messages for the server sent events (SSE), and a custom Kafka Connect transform kafka-connect-json-schema transforms these messages and then the messages are written to a Kafka cluster. This example uses ksqlDB and a Kafka Streams application for data processing. Then a Kafka sink connector kafka-connect-elasticsearch streams the data out of Kafka and is materialized into Elasticsearch for analysis by Kibana. Confluent Replicator is also copying messages from a topic to another topic in the same cluster. All data is using Confluent Schema Registry and Avro. Confluent Control Center is managing and monitoring the deployment.

Confleunt demo (cp-demo) coughs on jq. How to add to docker?

Asked 2020-Feb-18 at 23:00

I am trying to run the Confluent demo (which I cloned from https://github.com/confluentinc/cp-demo).

I get through all the steps up to starting the services in docker. This command:

/usr/mferris/cp-demo/scripts/start.sh

spits back:

ERROR: This script requires 'jq'. Please install 'jq' and run again.

I can install jq using brew—but that doesn't put it into my docker image. If I try to pull it into docker with: docker pull jq

I get:

Install below dependencies on your host machine and then run start.sh, you don't need jq in docker image, this is used by stasrt.sh script for json parsing

QUESTION

How to access Kafka Connector (confluent log connect) in a docker enviroment

Asked 2019-Nov-19 at 22:18

I am currently working with kafka based on confluent's cp-demo project. (https://github.com/confluentinc/cp-demo)

I am developing a custom connector which I was able to publish in the connect docker, however it is not working properly and I am having trouble accessing the confluent log to check how it is working.

I know about the existance of confluent log connect command which in my localhost enviroment allows me to access the log. How can I access this very same log in this docker environment?

Can anyone show me the path?

Thank you in advance!

confluent cli command doesn't exist in the containers. You would just use docker logs <>, or similar with docker-compose logs

Echo socket service in Spring Integration DSL using Channels and Gateways

Asked 2019-Mar-31 at 23:59

This is variant of my question How to implement simple echo socket service in Spring Integration DSL. A good working solutions was introduced but I would like to explore alternatives. Particularly I am interested in solution based on using inbound and outbound channels explicitly, in client and server implementations. Is that possible?

So far I was able to come up with:

You can't start the server-side flow with a channel.

The flow starts with the gateway; it handles all the socket communication. When is receives a message it sends it to a channel.

You could do this...

QUESTION

How to route using message headers in Spring Integration DSL Tcp

Asked 2019-Mar-20 at 14:39

I have 2 server side services and I would like route messages to them using message headers, where remote clients put service identification into field type.

Is the code snippet, from server side config, the correct way? It throws cast exception indicating that route() see only payload, but not the message headers. Also all example in the Spring Integration manual shows only payload based decisioning.

...

ANSWER

Answered 2019-Mar-20 at 14:39

There is no standard way to send headers over raw TCP. You need to encode them into the payload somehow (and extract them on the server side).

The framework provides a mechanism to do this for you, but it requires extra configuration.

See the documentation.

Specifically...

The MapJsonSerializer uses a Jackson ObjectMapper to convert between a Map and JSON. You can use this serializer in conjunction with a MessageConvertingTcpMessageMapper and a MapMessageConverter to transfer selected headers and the payload in JSON.

I'll try to find some time to create an example of how to use it.

But, of course, you can roll your own encoding/decoding.

EDIT

Here's an example configuration to use JSON to convey message headers over TCP...

QUESTION

How to implement simple echo socket service in Spring Integration DSL

Asked 2019-Mar-18 at 01:21

Please,
could you help with implementation of a simple, echo style, Heartbeat TCP socket service in Spring Integration DSL? More precisely how to plug Adapter/Handler/Gateway to IntegrationFlows on the client and server side. Practical examples are hard to come by for Spring Integration DSL and TCP/IP client/server communication.

I think, I nailed most of the code, it's just that bit about plugging everything together in the IntegrationFlow.

There is an sample echo service in SI examples, but it's written in the "old" XML configuration and I really struggle to transform it to the configuration by code.

My Heartbeat service is a simple server waiting for client to ask "status", responding with "OK".

No @ServiceActivator, no @MessageGateways, no proxying, everything explicit and verbose; driven by a plain JDK scheduled executor on client side; server and client in separate configs and projects.

HeartbeatClientConfig
