When we shard a collection MongoDB distributes its data across all the shards of the cluster. MongoDB uses chunks, split and round balancing for getting it. For all of you who want to read about it here it is our last post MongoDB Pre-splitting. This is how MongoDB allows our […]
Some days away since the MongoDB Workshop I made with the students (Bachelor and Master Degree) of the Escuela Superior de Ingenierías of the University of Huelva.
In Two steps to shard a MongoDB collection and What is a MongoDB chunk? posts we explained how to shard a collection, what a chunk is, which of them are moved when our system is not balanced and what shard will be its destination. Today, we are going to use […]
We have already studied the chunk concept What is a MongoDB chunk? and also how MongoDB splits it when grows beyond the maximum size established by default Four steps to split a MongoDB chunk. At this post we are going to study the steps that MongoDB follows to balance our […]
This is the second part of the post What is a MongoDB chunk? What are the steps for splitting a chunk? All the mongos store information about the size of the chunks of all of the shards. When a mongos realizes that a chunk has been written a lot, it asks […]
We already know that MongoDB is capable of keeping our cluster balanced for one or more collections (Two steps to shard a MongodB collection). This is done chunk-based (per shard), it is not document-based or size-based. What is a chunk? But, what is a chunk? To get our data evenly distributed […]
