amazon web services - Inner workings of an elastic search? -

-

I want to learn how elasticsearch works I have had concerns about the scalability of my design. I have 50 million documents, each document has approximately 50 string properties, 45 integer properties and 5 date time properties.

So my worries are when I query the E with E, containing the date of 8 fields and 3 sorting based on date and integer values. How does ES do? What happens in the background, so when the system reaches 500 million, I ensure that performance?

The link is a good start to understand what the comment is going on. But you do not have to understand everything to work things out. Good thing on elastic search - it's elastic means, it's very well scales , so if you need more performance then you have more RAM / CPU / server You can add and maybe configure the cluster (well, at least then you should learn something about shards and nodes).

BTW, your scenario is not very difficult for Lucene (which is ES based), if you need to query under the second or more, we use the same settings with & gt; 200M documents on a single medium range server (approximately 2500 euro). I encourage you to create a real live test on your desktop / laptop indexing 50m backs. We have also done this

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
