How do I find the C# Documentation for Nesper?

QUESTION

How do I find the C# Documentation for Nesper?

Asked 2018-Dec-06 at 19:56

I already read the Java documentation. Unfortunately the Java API and C# API are quite different.

I am trying to implement a CSV-Adapter for the Nesper CEP Framework.

Thanks in advance!

Thanks to the EsperTech Support Team, I found out that they do not have a seperate documentation for NEsper but the official actually appeals to both (Java and .NET).

They also mentioned that the Regression project in the main NEsper prject is a good reference if you need examples.

I think the best examples are in the Examples folder of the NEsperAll.sln project.

QUESTION

Using NEsper to read LogFiles for reporting purposes

Asked 2018-Aug-16 at 11:51

we are evaluating NEsper. Our focus is to monitor data quality in an enterprise context. In an application we are going to log every change on a lot of fields - for example in an "order". So we have fields like

Consignee name
Consignee street
Orderdate

....and a lot of more fields. As you can imagine the log files are going to grow big.

Because the data is sent by different customers and is imported in the application, we want to analyze how many (and which) fields are updated from "no value" to "a value" (just as an example).

I tried to build a test case with just with the fields - order reference - fieldname - fieldvalue

For my test cases I added two statements with context-information. The first one should just count the changes in general per order:

To 1), yes

To 2) this is valid, your EPL design is probably a little inefficient. You would want to understand how patterns work, by using filter indexes and index entries, which are more expensive to create but are extremely fast at discarding unneeded events. Read: http://esper.espertech.com/release-7.1.0/esper-reference/html_single/index.html#processingmodel_indexes_filterindexes and also http://esper.espertech.com/release-7.1.0/esper-reference/html_single/index.html#pattern-walkthrough Try the "previous" perhaps. Measure performance for each statement separately. Also I don't think the CSV adapter is optimized for processing a large file. I think CSV may not stream.

To 3) check your code? Don't use CSV file for large stuff. Make sure a listener is attached.

Vulnerabilities

No vulnerabilities reported

Install nesper

This is the more manual setup approach:.
It's recommend to copy nesper/esp-idf-examples/simplewifi example project initially, to get the proper build steps. git clone https://github.com/elcritch/nesper cp -Rv nesper/esp-idf-examples/simplewifi/ ./nesper-simplewifi cd ./nesper-simplewifi/ make build (also make esp_v40 or make esp_v41 )
Nesper wrapper API names generally match the C names directly, usually in snake case
FreeRTOS functions usually are camel case and start with an x, e.g. xTaskDelay
These api's are found under nesper/esp/* or nesper/esp/net/*, e.g. nesper/esp/nvs
Nesper Nim friendly api, usually in camel case
These api's are found under nesper/*, e.g. nesper/nvs
