We are currently investigating the IBM PROTON CEP for use in our system. But reading the documentation and trying it out we've come to the conclusion that the only way to program it is via one big JSON file.

In our case we have several hundreds of users editing their rules at the same time. Which means we have to make multiple edits to the JSON file per second and eventually end up with a really really big JSON file. How does PROTON deal with such a case or is it impossible to dynamically add/edit/delete rules made by hundreds of users while the CEP is running?

Is there any other way of programming the engine, does it support any database backing for the storage of rules that makes it possible to work with just a single rule instead of editing the whole file?

Thanks in advance.

Hello

I'm part of the SAF technical team working for PSNC, Poland. We want to have an insight of the process of membership for the SMEs (who are currently using FIWARE lab nodes) to FIWARE Foundation. We also want to have information about the status of FIWARE Foundation and the possible ways to be a part of it.

Thanks Sam

As the answer in the quoted FIWARE Q&A entry suggest the problem is fixed by now. its here: https://ask.fiware.org/question/79/co... However, it seems like other issues arisen related to the solution, namely: Through ssh connection, the typing the hive command results in the following error: https://cloud.githubusercontent.com/a... the hiveSQL queries work fine (through ssh) regardless the error message.

When launching exactly the same hiveSQL queries (each one of them worked flawlessly two weeks ago) remotely, the request times out even in absurd time windows (10 minutes). The most basic commands ('use $username;', 'show tables';) also time out.

(The thrift client is: https://github.com/garamon/php-thrift... )

Since the Cosmos usage is an integral part of our project, it is of utmost importance whether it is a temporal issue caused by the fixes or it is a permanent change in the remote availability (could not identify relevant changes in the documentation).

We have registered to Cosmos server. The user name allows to upload files. For database operation there is no need for further authentication. We can reach database and tables of any users. We noticed update to our table from outside.

So is Cosmos an open data processing environment? Or is it a malfunction?

Added a link to the screenshot of the php code: https://cloud.githubusercontent.com/a...

We are developing an Android application and want to authenticate our users based on the keyrock instance from the Fiwarelab (temporarily before installing our own Keyrock instance on our server). So we have imagined this being exactly like google or facebook sign in. We want to use the public and private keys provided while registering the app. The method (out the only two available) we have chosen is "Resource Owner Password Credentials Grant."

In our test authentication method we only created a simple code to check for username and pass. But we wish to use the esource Owner Password Credentials Grant that keyrock allows to use.

public void enter(View view){ onButtonClicked.start(); // if(cultureName == "Select culture") // { // Toast.makeText(this, "Please select culture!",Toast.LENGTHSHORT).show(); // } // else if(cultureName == null) // { // Toast.makeText(this, "Please check your internet connection!",Toast.LENGTHSHORT).show(); // } // else EditText user = (EditText)findViewById(R.id.editText1); username = user.getText().toString(); EditText pass = (EditText)findViewById(R.id.editText2); password = pass.getText().toString();

//if(username.equals("ad") && password.equals("ad")) {

  Intent intent = new Intent(this,MainActivity.class);
  startActivity(intent);
  IntroActivity.this.finish();

} //else { //Toast.makeText(getApplicationContext(),"Username or password are incorrect! Please try again!", Toast.LENGTH_LONG).show(); }

}

} Any kind of help, examples, hello world, would be more than welecome. Thank you!
