I have an application using a PostgreSQL database with multiple backend-API's. Because we some times run out of connections, I would like to be able to identify which backend API has active connections in view pg_stat_activity. Is it possible to identify the connection from node pg-postgres?
What you see (in pg_stat_activity) is what you get. If none of those fields are helpful, then I guess the answer is no.
Aren't all the APIs pooled together through the same shared connections?
Application_name could help if you can convince node.js to set them per API. query text could help if you recognize what query text is from which API.
I want to read data from Hadoop and make it available in memory through SparkSQL so I can use a NodeJS application to access it with low latency.
Since the data is sensitive I need to ensure whoever is accessing this thrift server instance has the required access.
I don't know too much about thrift server with Spark but I understand that I should provide a username and password in my application to authenticate against the server.
How can I do that? Define a username and password in my Thrift or Spark code/environment and use that in my JDBC / ODBC calls?
Thanks!
Consider the scenario: a client app sends me the name of the table I need to get data from and additional information such as date range. How can one construct such queries safely? I use nodejs as my backend and influxdb as data store.
What tools can you use to monitor or access data in use on a Node server? A comparison would be using the Javascript Console for a browser and being able to console.log a variable value to the console or execute methods. Is there something similar you can do with a NodeJS server?
Edit: An example; if I deployed my server to an AWS ec2 instance could someone managing the datacenter theoretially access my server and monitor/view the data in use? If so, how?

I am making one Java ME Application. Here I am using HttpConnection for making Connection with webservices. I send/Receive data using HttpConnection, DataInputStream & DataOutputStream. But My Problem is that How can I check that currently GPRS connection is available or not ?
I got, System.getProperty("com.nokia.mid.networkavailability"); API to check the Network's Availability. But I want to know how to check if GPRS is available or not ? Help Me Regarding this. ( I am using Nokia's E5 Phone for Development work ).
Based on this article, You can use the following property for getting the network access type of used active connection or a set default access point.
String value = System.getProperty("com.nokia.network.access");
Also you can read this article, IAP Info API in Java™ ME. It will helps you.
