How to configure Cygnus to save data on SQL database?
After installing Orion and Cosmos, I try to configure cygnus and save data on mysql database. Is it possible?
With Cygnus you can save all the entities you want to by making a subscription to OrionCB. Yo can save it in differents formats including MySQL.
Anyway, you should visit this Cygnus guide and read it before asking about. The guide is pretty clear about how cygnus work.

I am trying to learn kafka technology and I want to setup a small pipeline in my pc which will take data from mysql and parse them into a kafka cluster.
For a small research that I made, I saw that the best way for this is KAFKA CONNECTOR.
Can someone please help with tips or information about how to implement the above logic?
The easiest way would be to use the JDBC Source connector to pull data from your MySQL server to Kafka topic for further processing. Please find the link to the Confluent JDBC source connector. Please view the various configuration the connector offers to better align your data for subsequent processing.
So I have an SQLite3 database with Sequelize on a VPS and a Website I hosted on Hostinger.
Is it possible to access and edit the data in the database from the website?
Any help is appreciated.
[my code is in nodejs]
Yes and No.
Easy and simple answer - now;
Longer - yes, but you would need to map the directories, so server running your sequelize will think it accesses normal directory.
You can download the database, edit it and then send it back. sqlite3 is file database, you dont really connect to it (usually)
SQLite is a database format based on a single file. It's simple but not massively performant. It has no networking features.
The SQLite client needs to have access to the filesystem that the database lives on.
If they are on different computers, then you could do it by using some kind of network filesystem (e.g. via fuse) but this would be really slow.
A better approach would be to run a webservice on the computer the file is stored on, and access the database through there.
I have just completed a Spring Boot tutorial of 34 videos. Im looking online and everything seems to show me how to create persistence of my data when the spring application is running. However, once I stop the program and restart it, it doesn't have the data I want saved.
So what it sounds like is I need to store this information on a database. I think I've set up a MySql server on my laptop and I have the workbench app/interface.
What might be more appropriate is connecting to an online server that I have with phpmyAdmin. In any case, how do I connect my spring application to a database instead of to a localhost:8080
Please let me know where I can look and what resources I have here as I'm kind of new to this sort of thing. Much appreciated!
There 2 options
Either use persistent DB instead of in-memory storage
You are using spring.jpa.hibernate.ddl-auto=create-drop hibernate property that will recreate db schema every time you start the application - thus its "clear" of the start. Use update or validate instead.
Maybe you can set spring.sql.init.mode=never to not always initialize your database using scripts.
This way you'll find all data you saved even when re-run the app.
I am very new to DB.
Is it possible to transfer data from LDAP server to mysql?
Also is it possible to transfer data from LDAP server to elasticsearch?
I am using Grafana and trying to integrate it with LDAP data (if possible directly)
Since Grafana can connect with MySQL and Elasticsearch, I want to transfer data from LDAP server (ldif , csv, or any) to MySQL or Elasticsearch.
If anyone had done this before, could you give me some tips on how?
I think you can do that with slapcat: https://serverfault.com/questions/435261/ldap-export-and-import
To import into mysql or similar, you'll have to understand the dump format and put it into mysql.
Recently I started a project where it is required to access a MySQL server hosted on hostgator's server from a WCF project. I downloaded and installed MySQL ADO.NET connector and tried to create an entity data model but it says Authentication method 'mysql_old_password' not supported. What should I do? I have been googling but to no avail.
This is my first time using MySQL.
Any help would be greatly appreciated.
Thanks in advance

This error message is shown when you are connecting to a MySQL database that has its passwords stored in the old password format (http://dev.mysql.com/doc/refman/5.0/en/old-client.html). Newer MySQL clients do not allow a connection to be made to databases using the old password format as it is less secure.
Some would suggest to set old_passwords=1 at the MySQL server, but I think it would be better to upgrade the passwords to the new password format. Then the MySQL connection can be setup again and your database will be better protected.
You can read about how to upgrade your MySQL passwords from the old format to the new format here: http://code.openark.org/blog/mysql/upgrading-passwords-from-old_passwords-to-new-passwords
