java - How to achieve a bounded model in DynamoDB? -

-

I have issues with the following:

I have a list of sorted user events in DynamoDB I want to keep in the descending order, as if I look at the latest events at the top, however, I only take an interest in the latest 1000 events.

At the moment I have a table with the user id as the hash key, and the timestamp of the user event as the range.

Is any effective measure with a maximum of 1000 to keep the number of items in the range for any user, first with the latest events?

I am using Java lower-level API, if it matters.

I think your table schema is perfect, you can ask the table with the user id More options can be used 

  ScanIndexForward = & gt; False   
 This will sort your data in descending order on the boundary key (which is the timestamp)  
 and you can use the option  
  range => 1000   
 This will display only 1000 programs.  
 Hopefully

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] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
