An endpoint configuration section for contract could not be loaded because more than one endpoint configuration for that contract was found. Please indicate the preferred endpoint configuration section by name

Introduction

This fix explained here is helpful if you are using WCF and when you try to access the service, the client throws an exception like “An endpoint configuration section for contract ‘YourContract’ could not be loaded because more than one endpoint configuration for that contract was found. Please indicate the preferred endpoint configuration section by name”.

How to fix this exception

WCF service can expose more than one endpoint and client can use any of this endpoint but not more than one at a time. This type of exception occurs when you have more than one endpoint configured at your configuration file (app.config) file while adding service reference or while configuring service at client side manually. You can have only one and only endpoint for the client. If you are getting this exception then check your client side configuration file and make sure the client tag under system.serviceModel has only one endpoint configured.

<system.serviceModel>
   <client>
      <endpoint [...]>
     </endpoint>
   </client>
</system.serviceModel>

Parquet file experiments, findings and recommendations

Parquet is a binary file format designed with big data in mind where we must access data frequently and efficiently. The way it stores file on the disk is also different from other file formats. It is a column-based data file. And in reality it uses both row based and column based approach to bring the best of both worlds. The data is encoded on disk which ensures that the size remains small compared to actual data and is then compressed where the file is scanned as whole and cut out redundant parts. The query/read speed is dramatically fast when compared to other file formats. Nested data is handled efficiently which is quite cumbersome in other file format to achieve. Doesn’t require to parse the entire file to find data due to its way of storing data. This makes it efficient in reading data. Works quite efficiently with data processing frameworks. Automatically stores schema information. SQL querying is possible with this file format using Continue reading

I have wide range of interests and getting my hands dirty in technology is one among them. I use this platform primarily as my knowledge base. I also use this platform to share my experience and experiments so that it might help someone who is walking the way I already did. The suggestions expressed here are the best to my knowledge at the time of writing and this may not necessarily be the best possible solution. I would pretty much appreciate if you could comment on it to bring into my notice on what could have been done better.
