如何覆盖由WSO2DAS设置的事件时间戳记

Question

Currently WSO2 Data Analytic Server set the current timestamp to every event received using the available APIs. Is there a way to pass the timestamp value on the event data over the APIs in order to sent historical events to DAS?

Answer 1

From DAS 3.1.0 RC 1 onwards this can be achieved. You can follow the steps below to try it out.

1. Download DAS 3.1.0 RC1 from here .
2. Create an event stream with your payload and also add an attribute named _timestamp and set the attribute type as long .
3. Persist the Event selecting your payload attributes. (Please note that you will not be able to select the _timestamp attribute so leave it as it is)
4. Now simulate a event by providing your payload data along with the _timestamp epoch eg - 1450206041000. The data explorer will show you an event received in 2015-12-16 00:30:41
