Understanding grain references and UniqueKey for Orleans CosmosDB provider

As a part of enabling custom partition keys on the cosmosDb provider I wanted to get a better understanding of the id used in the documents stored in CosmosDB, so

scalability

Easy scaling with Cosmos DB for large loads

Working with a customer we need to load a batch of 40-50K documents to Cosmos DB. We could let this pass, but it will result in quite a few HTTP

Default indexing in Cosmos DB

I recently needed some paging functionality in Cosmos DB, since skip and take is not directly supported we're using a cursor based paging based on a date time. While testing

Notes on the new DocumentDB partitioning and pricing

The new pricing scheme and partitioning functionality for DocumentDB, made available at Build, was a significant improvement to the DocumentDB offering. I learned about this a few weeks beforehand, but

Indexing changes in DocumentDB

Benefits of having an open source project

During Desember last year I created an open source project called DoubleCache. It's a cleaner version of a cache pattern we use at work, written from scratch. TL;DR Great source for a conference talk Helped me learn FAKE and Appveyor Made me reason

Unit testing Redis Lua scripts

With great power comes great responsibility. The power of Lua scripting with Redis and what you can achieve using data structures beyond a key/value store is amazing. Starting out is quick and easy, and with some VIM tricks you can easily create an

Turn up the beat, heart rate of a speaker

Beginning of January I was contacted by the Bitshift meetup organizers, asking if I could come over and do a talk or two. Having two talks more or less prepared I decided that it could be a fun experience and also great practice. I

Isolating failures - deliver what you can

If some of your functionality fails, should it take your website down? Let's say you have a frontpage of a webshop displaying promoted items, a campaign and a list of the most popular items. If you fail fetching the popular items, or have some

Introducing DoubleCache

DoubleCache, https://github.com/AurumAS/DoubleCache, is my own open source implementation of a layered distributed cache, it builds upon solid projects like Redis, StackExchange.Redis and MsgPack and combines these with a local cache implementation on the .Net stack. Some history We're already

Single digit response times

Single digit response times are fully possible. And I think we should try to get there, it may not always be possible but that's no reason not to explore our options. A fast site will feel more responsive, and using less resources means that

Availability in an unreliable cloud

One of the first problems to solve when moving to the cloud is availability, or just plain uptime. Although it seems strange that the cloud should not be stable, but this is one of the constraints that is an enabler for solid solutions. By

Patterns and Practices for Cloud development

Earlier this month, the developer team at Microsoft Norway managed to hijack Masashi Narumoto and Christopher Bennage from the Patterns and Practices team while they were in the UK. The short stop in Oslo was highly appreciated with a packed theater. Now, we might

Black Friday failure

Black Friday gained traction here in Norway the last years, and this year was bigger than ever. As Cyber Monday is still very small, most online stores run their offerings on Friday as well. This lead to what can best be called a nationwide

Versioning messages on Azure Servicebus

We currently found our self in a tight spot, a somewhat careless refactoring broke our protobuf format. As we are in multiple datacenters we need to handle 2 versions at a time during transitions between versions. This was not totally unexpected, however the problem

NDC London Videos

NDC London published their videos some time back, and I finally managed to look through the list and compile a "short" list of talks I would like to see. The reasons for why I picked these vary. A mix of things I'm

RFC what?

Request for Comments is a series of publications which define how the internet works. These are the papers that form our world. To my disbelief, a lot of developers have not read a single one. Imagine how you would feel if the mechanic working

Getting started with Azure Redis Cache

We recently switched some services from Azure managed cache to Azure Redis cache due to stability and connectivity issues. The transition went almost without any issues. In this post I will give a basic introduction to Redis on Azure and pointers to look at.
