nosql performance benchmarks

performance is significantly different for applications that work in different application scenarios. Different NoSQL products have different applicability. 6. Secondary indexes help to sort and query non-primary key fields. Some NoSQL products do not provide such functions. 7. fault handling different application scenarios have different fault recovery time tol

I remember that I wrote MySQLvsNoSQL more than half a year ago, and I have always insisted on using a database to store KV data, because it not only guarantees data security, it is mainly found that the qps of most systems is not that high at all, and the level of 4 K is very small, which MySQL can fully meet, because the optimized KV request can be implemented on the MySQL SQL layer. I remember writing MySQL vs NoSQL more than half a year ago, and I

). limit (10) // Ignore the query statement here It was very efficient, and the result was just a few milliseconds. It was really top-notch in NoSql efficiency. However, it is slow. I only use 10 data records, and there is not much data. I added the data to 100000, and the efficiency was about 20 ms. If such a simple study is over, it is really disappointing the spirit of programmers to study. The SQL paging solution has different efficiency because

Among many nosql products, what we can see through benchmark is that the write performance is greatly improved, while the read performance has not increased much or even declined from the traditional RDBMS. For example, Cassandra and MongoDB are two outstanding representatives of nosql. The reason may be that the UGC m

January 18, 2012, Amazon released Amazondynamodb, a fully managed, high-performance, high-reliability, cost-effective NoSQL database. Dynamodb is ideal for Internet-scale applications.The DYNAMODB database incorporates Amazon's many years of experience in large, non-relational databases and cloud computing. As early as 2007, Amazon published a paper that delves into the design concepts and implementation te
