Cassandra may not be interested in being a nosql, but it's fascinating to do certain jobs, as Netflix and Instagram two companies must know.Over the years, NoSQL participants, such as MongoDB, have gotten a lot of attention, but the halo of Apache Cassandra has faded, and Facebook, which created Cassandra, has given up on it, The community of Cassandra seems to be out of date soon.

Comparison and Analysis of eight common NoSQL Database Systems
Krist óf kolács is a software architect and consultant who recently published an article comparing various NoSQL databases.
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
As we all know, relational data types have always been one of SQL's criticism. With the increasing variety of data, the conversion from various data types to relational data types has plagued most SQL database users. However, the advantages of SQL databases are undeniable. If you can have both the fish and the bear's paw-implementing nosql Data Types in the SQL database, isn't everything a wonderful change ?!

In-depth analysis of distributed algorithms for NoSQL Databases
System scalability is the main reason for promoting the development of NoSQL, including distributed system coordination, failover, resource management and many other features. In this case, NoSQL sounds like a big basket, and everything can be inserted. Although the
NoSQL series: Why use NoSQL databases when appropriate databases are selected? The impedance imbalance relationship model does not match the data structure in the memory. More convenient data interaction methods are used to improve development efficiency. The amount of data to be processed is large. The amount of data exceeds the capacity of the relational database. large clusters appear in the cost aspect.
transactions in the database (transaction) have ACID4 basic features that can be compared to trading:1,A (atomicity) atomicityEverything in the transaction is either completed or failed during execution and is rolled back.2,C (consistency) ConsistencyThe database should be in a consistent state.For example: Existing integrity constraints a+b=10, if a transaction changes A, then B must be changed3,I (isolation) IndependenceThe concurrent transactions do not affect each other.If the data to be acc

Because the associated query requires other nodes to provide data sharding , one query needs to mobilize other nodes, so concurrency performance will be very poor.This kind of lightweight distributed database system, which can only guarantee weak consistency, is a NoSQL system , which removes the correlation.NoSQL is the most used when the number of key-value storage, of course, ther

At this point you need to go to each of the sub-table query and then the query results are assembled. And the native SQL is not complete. When an index is unavailable, the aggregation operation is certainly not allowed. SQL or NoSQLSo you can see that SQL is
