Difference between MongoDB and Couchbase
2
A significant database server MongoDB with its
great specification for elective storage engine
called Wired Tiger. It has a provision of writing
capability for the MongoDB server about 10 times
more than the normal one. For data
standardization the data need not be kept in the
memory. The number of read and write operations
performed with both the servers is the same.
Outside the memory, the data is used and it well
explain us the ways these two servers perform.

• Data Model
• Both documents and key value can be seen din
  Couch base in terms of data models, but the data
  model is only document type in MongoDB. Every
  document will start with a key value as the
  documents have their keys. Both query and index
  services can be used for the query.

• Concurrency
• The couch base server in terms of concurrency has
  both pessimistic as well as optimistic locking
  whereas MongoDB server also has the same but with
  an optional store machine known as WiredTiger.

• Storage
• The capacity of holding the binary values about
  20 MB whereas MongoDB server has the ultimate
  capacity for storing huge files into a number of
  documents. The server can have larger binary
  values and still continue to

• Scaling
• Master-master scaling model is distributed as a
  Couchbasewhile the MongoDB has both master and
  slave duplicate sets as its scaling model. From a
  particular duplicate set it is very tough for
  MongoDB to set an entirely fragmented frame.

• Fragmentation
• The data is fragmented by the Couchbase and then
  counts horizontally by spreading hash space for
  all the nodes in the cluster of data. The key
  present in the each document decides the
  particular node of hash space.
