Yangchuanhui, CTO of oceanbase: some HTAP databases are not real htaps

Please pay attention to my official account.

OceanBase CTO Yang Chuanhui , Recently OceanBase An article was published on the official account. ： real HTAP What it means for users and developers ？ This article is very well written , Mr. Fei strongly recommends that yes HTAP Interested people read this article carefully , By the way, let's talk about a very important point .

Here I quote his original ：

There are also some solutions of two systems in the industry , for example OLTP System USES RocksDB/MySQL,OLAP System USES Spark perhaps ClickHouse, And implement different types within the system SQL Routing distribution of . This scheme does not conform to “ A piece of data “ The requirements of , Not really HTAP. Why? ？ Because the adoption of the two systems will inevitably lead to a sharp rise in costs , For the high availability of the system ,OLTP Systems and OLAP The system needs to have its own independent multi copy disaster recovery architecture , And the two systems cannot guarantee the consistency of data in theory . Yang Chuanhui , official account ：OceanBase real HTAP What it means for users and developers ？

This view of this article , Fei always agrees . If a system actually stitches two different systems together by stitching , So this is a “ Stitches are weird ”. Stitching monsters are certainly not real HTAP System .

And there are also various problems in the subsequent development and development of this kind of sewing monster . for instance OLTP The system could be Go Written ,OLAP System is C++ Written , Bonding together is troublesome . Maybe the same Aggregate function , I not only use Go Let's do it again , And use it C++ Do it again , Also ensure that the semantics of both sides are consistent .

Is it troublesome ？ Listen, your head is big . Upgrade every system in the sewing monster , Will lead to all kinds of problems , Think about how to develop in the future , It's big enough .

But there are suture monsters who vigorously promote that they are awesome HTAP System , You can do OLAP Can also handle OLTP Of , Deeply sought after by investors , And the ignorant public on the Internet .

OceanBase CTO Yang Chuanhui directly lit up this view , Tell you why these systems are not real HTAP, I still admire people who tell the truth . After all , He can also not offend his peers , A little careless eye , It's over . Hello, I'm Hello, everyone .

Some might say , That's because OceanBase I'm not a stitcher , That's why he belittled others as suture monsters .

The problem should not be viewed in this way ,OceanBase Why not a stitcher , Because OceanBase People know what is right and what is wrong , Chose to do the right thing .

Some other products , Also know what is right and what is wrong , But I know more about what is complicated , What is easy to do . It can be done simply , Why must it be complicated ？

So some products choose simple but not necessarily correct solutions , At the same time, vigorously publicize the right to speak . Investors , Probably willing to pursue these new things .

As for whether you will be fooled by these new things , It depends on whether the early investors go in later , Early investors have long been full of money , Go in the back , Pan Xia, congratulations .

Already connected , I can only bless you , The current economic situation is not good , If you want to go public, let the majority of shareholders leeks continue to pick up your plate , It's really a little difficult .
