I am trying to connect my nodeJS with Apache ignite regular(thick)client, but i am unable to find any proper documentation or example of that.Can anyone suggest what are the steps for that.
As far as know thick Ignite client hasn't been implemented yet. Anyway you should be able to use thin Node.js client.

I would like to implement an RPC system with NodeJS and Java client using Apache Pulsar. Unless there is already one, would you have any advice to implement this?
I'm trying to use Apache Flink's Table concept in one of my projects to combine data from multiple sources in real-time. Unfortunately, all of my team members are Node.JS developers. So, I'm looking for possible ways to connect to Flink from NodeJS and query from it. In Flink's documentation for SQL Client, it's mentioned that
The SQL Client aims to provide an easy way of writing, debugging, and submitting table programs to a Flink cluster without a single line of Java or Scala code. The SQL Client CLI allows for retrieving and visualizing real-time results from the running distributed application on the command line.
Based on this, is there any way to connect to Flink's SQL client from NodeJS? Is there any driver already available for this like Node.JS drivers for MySQL or MSSQL. Otherwise, what are the possible ways of achieving this?
Any idea or clarity on achieving this would be greatly helpful and much appreciated.
There's currently not much that you can do. The SQL Client runs on local machines and connects to the cluster there. I think what will help you is the introduction of the Flink SQL Gateway, which is expected to be released with Flink 1.16. You can read more about that on https://cwiki.apache.org/confluence/display/FLINK/FLIP-91%3A+Support+SQL+Gateway
Another alternative is to check out some of the products that offer a FlinkSQL editor on the market, maybe that is useful path for your colleagues.
For example:
https://www.ververica.com/apache-flink-sql-on-ververica-platform
https://docs.cloudera.com/csa/1.7.0/ssb-overview/topics/csa-ssb-intro.html
Note that this is not exactly what you asked for, but could be an option to enable your team.
I am using Titan graph db with Cassandra and Elasticsearch, Node.js and building RESTful web services.
I am confused whether to connect to Gremlin server using HTTP or Web Sockets.
Please share your learnings and let me know if there are any good reads or video tutorials on this.
Note: Titan is no longer maintained, you should switch to JanusGraph, which was forked from Titan and is maintained by an active community of users and developers.
You can use https://github.com/jbmusso/gremlin-javascript which can be found in the "Language drivers" section of the Apache TinkerPop site.
You can find sample code in https://github.com/jbmusso/gremlin-javascript/tree/master/gremlin-client
I am trying to figure out how to connect to Hbase(0.98) using Nodejs. I have tried using hbase-client but that is for hbase 0.94 and below. Can anybody guide me on how to go about it?
To make it simple I would use the REST API (or thrift if you are familiar with)
I'm new in Node.js. I'm trying to find out and learn which is the best way to set an Api Server, just for CRUD (Create, Read, Update and Delete) requests.
I've being looking around the different server frameworks that are normally used with Node.js:
Express
Restify
Hapi
I'm also using the node-postgres library already connecting to the database and making queries, but I haven't found a good guide or example using either of the previous frameworks to set an Api Server with PostgreSQL.
I'd be very thankful is someone could point me to the right direction or show me a basic example.
Thank you
Hapi has the best performance. Otherwise I hope this can help you:
