Editor to share with you what are distributed databases in the database, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article. Let's learn about it together.

Distributed databases are: 1. The direction of the Internet of things, time series database products, to meet the collection, storage and statistics of IoT data, such as InfluxDB, Kudu, kdb, OpenTSDB;2, transaction relationship direction, Ant Financial Services Group Oceanbase, Tencent TDSQL.

Distributed database products on the market are divided into several categories:

1. The direction of the Internet of things: time series database products to meet the collection, storage and statistics of IoT data. Temporal database products also have the greatest impact on in-memory database products. For example: InfluxDB, Kudu, kdb, OpenTSDB

2. Transaction relationship direction: replacing traditional transaction relational database products such as Oracle/DB2 can not meet the online trading business scenarios of massive throughput, massive concurrency, massive trading and mass storage. For example: Ant Financial Services Group Oceanbase, Tencent TDSQL, Repu HotDB, ZTE GoldenDB, open source MyCAT, open source Cobar.

3. Analyze the relationship: solve the business scenarios of structured data storage and data analysis, such as Greenplum, Vertical, Gbase8a, etc. However, this piece has received a huge impact from KV analytical products.

4. KV analysis direction: Hadoop and Spark are the cornerstones at present, and many domestic and foreign companies do secondary research and development on the basis of them, especially to achieve compatibility with SQL standard syntax, which has catered to business scenarios and R & D personnel.

5, KV document direction: to solve the online document type of unstructured data storage and data processing, such as: MongoDB, giant shirt SequoiaDB, but are also desperately compatible with SQL standard syntax.

6. HTAP: transaction analysis hybrid distributed database products, from the perspective of technical principles, this is not supported by theoretical innovation, but the good wishes of our technicians, such as domestic TiDB, foreign Spanner/F1 (no one knows what it looks like and what the experience is).

Each route has its own specific algorithm, specific architecture, and product characteristics, and it is difficult to have a product that is fully compatible and performs well.

These are all the contents of the article "what are the distributed databases in the database?" Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
