In particular, PostgreSQL, the PostgreSQL database scored a significant decline in the September rankings (-11.07), last month, open source China has reported, according to this trend, MongoDB may be expected to push PostgreSQL fourth place this year. s position. But this month, PostgreSQL became the database with the highest score growth with a growth of 12.97 points, and once again, MongoDB lost a segment.
Another Oracle that scored more than 10 points was equally eye-catching, with scores falling in the September rankings, and this month's score increased by 10.15. MongoDB has remained stable and continues to grow at a steady rate. As of October, MongoDB's score has been growing for 12 months, and this record can be maintained in the top 20 databases. Although Redis experienced a lot of storms in September, compared with last month, it still advances to a ranking, surpassing Elasticsearch and ranking seventh with a slight advantage.
There are no other changes that are worthy of attention in other areas. For a full list, please see https://db-engines.com/en/ranking
Let's take a look at how these well-growth databases have experienced last month.
Let's talk about Oracle Corporation. In the last month, Oracle experienced personnel turmoil, which caught the attention of the whole industry. Thomas Kurian, No. 2 of Oracle Technology System, officially left Oracle in September. Although it is not known, the transfer of Oracle on the cloud is obviously the root cause. Some people blame the implementation of the Oracle cloud strategy on TK, and there is also a rumor that Ellision hopes to soar Don Johnson. The reason is unknown, but it is said that Oracle's share price has been improved.Maybe sometimes the change breeds hope.
take a lookDon Johnson's resume on LinkedIn, it turns out that this is an AWS cadre. At Oracle, it is basically a level of promotion every year. Senior Director to Vice President, then to Senior VP, obviously becomes the core technology of Oracle Cloud Transformation.. Say that Silicon Valley is a family, do this home. Just don't know where Thomas Kurian will be next stop? Originally hopeful to compete for Oracle CEO's big BOSS, now free.
So now Oracle's situation is that not only is Don Johnson soaring, but before the role of TK is publicly announced, all TK's subordinates will now report directly to Larry Ellision, which isEveryone has risen to the next level. Can this be a big joy??
Redis’ recent fight is also on the scene, and Redis Labs’ CTO has recently smashed it.cloud serviceBusiness:
databaseDevelopmentRedis Labs this week changed the Redis module developed by the company from AGPL to a combination of Apache v2.0 and Commons Clause (shared terms), thus limiting the software covered by the sales license.
The new license limits the ability of cloud providers to offer these Redis modules to customers; Redis Labs may be intended to be a vendor of services that include these add-ons. However, the Redis database code still uses a BSD license.
Yitsach Shoolman, co-founder and chief technology officer of Redis Labs, gave a reason for this change in licenses in a blog post on Wednesday, claiming that cloud providers benefit from open source software. But did not give any return.
In September, Redis experienced a change of name. Because the use of master-slave was accused of being discriminatory, it was forced to announce its name change, citing a paragraph of text, and watching the officials watch the war:
Master/Slave mode is a commonly used computing structure in distributed systems. The word begins with the MySQL database, mainly representing the master-slave replication function provided by the MySQL database itself. With master-slave, multiple automatic backups of data can be conveniently implemented to realize database expansion. Multiple data backups not only enhance data security, but also improve database load performance by enabling read and write separation.
The noun is a combination of two words: Master and Slave.
Master: Master, employer. Slave: slave, slave.
As people begin to pay more and more attention to human rights, discrimination and other issues, many developers believe that this description is invasive. So, there are a lot of voices calling for a modification of this description. Their main appeal is not to use
Master-slaveInstead of using this vocabulary, use other words instead.
The reason why this matter has recently received so much attention is because the more critical technologies are required to be modified, that is Redis and Python.
Redis has made a change:
Change the description of the master-slave architecture to master-replica
Provides an alias REPLICAOF for SLAVEOF, so SLAVEOF can still be used, but with an additional option
Keep using slaves to respond to INFO and ROLE, which is now still a major disruptive change
Write an alternative to INFO
There are a lot of things to replace inside. For technical reasons, if you make changes, many PRs will not be applied, so you have to make big changes in some places.
So take a look at Oracle's naming: Primary and Standby have a foresight! However aboutThe Redis debate also fully demonstrates the breadth and importance of this product..
If the database rankings in October Oracle and Redis are the two most noteworthy members, I believe that Redis's stamina is still fierce, and once Oracle wakes up, it is still the unrivaled overlord.
Finally, let's take a look at the top ten trend change graphs:
DB-Engines ranks the database management system based on popularity, and the rankings are updated monthly. The ranking data is based on 5 different indicators:
Number of keyword searches for Google and Bing search engines
Number of searches for Google Trends
IndeedwebsiteJob search volume
Number of profiles for keywords mentioned in LinkedIn
Related issues and number of followers on Stackoverflow
This list analysis is intended to provide a technical direction reference for database practitioners, and the rankings involved are not based on factors such as the technological advancement of the product or market share. Regardless of ranking, it is most important to choose a technology that is suitable for the business needs of the enterprise.
