nest - how we decide in which node we should store document in elasticsearch? -

-

Because I'm a new in ES, I need help.

I have read that it is possible to specify the noise where the document is stored using 'routing'. But is it possible to restrict that a document should be saved in a particular node? ..

Suppose I have two nodes node 1 and node 2 I need that, if I add a document from node 1 to index 'attenadence', keep it in the primary shard node 1 And replication can be on node2. And the same thing, if I add a document from node 2 to index 'attenadence', then it should store the primary shard in node 2 and the replication can be on node 1 ... please advise me that it is possible in ES? .. If so, please tell how to get it in ES.

There is a specific value associated with racks in cofig.yml in each node, node 1 has a setting node . Crack: Rack 1, a setting of node 2 node. Track: Rack 2, and so on.

We can create an index that will only deploy the rack on the nodes set on the rack setting index. Routing.allocation.include.tag for Rack 1. For example: 

  curl -XPUT localhost: 9200 / test / _ settings -d '{"index.routing.allocation.include.tag": "rack1"}' '  
 and ref:

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
