Introduction: Krist óf kolács is a software architect and consultant who recently published an article comparing various nosql databases. Article by agile translation-Tang YuhuaCompile. For more information, see post-Article declaration. Although SQL database is a very useful tool, after 15 years of outstanding performance, the monopoly will be broken. This is only a matter of time: I was forced to use relational databases, but I finally found that I could not meet my needs. However, the differe

Transaction design strategies for MongoDB, Cassandra, and HBase NoSQL databases (such as MongoDB, Cassandra, Hbase, DynamoDB, and Riak) make application development easier. They provide quite flexible data models and rich data types, and are easier to install and configure than many traditional database systems. Howeve

uses GridfsTo store files? Gridfs is a file specification that stores large files in MongoDB. Gridfs can be used to separate large files into multiple small documents, so that we can effectively save large documents, and solve the problem that the Bson object is limited. 7. Why is MongoDB data file very large? MongoDB uses a pre-allocated space way to prevent fi

space occupancy. I have suggested that the author put the field name index, each of the field names in one byte, so you don't have to worry about how long the field name takes. But the author's concern is not unreasonable, this index method needs to be a result of each query to replace the index value with the original value, and then send to the client, this substitution is also very time-consuming. Now the realization is to take the space to exchange time.3, delete the record does not free sp
