apache druid vs clickhouse

发布于 2021-02-20 03:02:13

I‘m a new to clickhouse, and already read "druid vs clickhouse", but still don't know which situation can use clickhouse. I know they are good OLAP engines。

Druid is an excellent timing database。 At large data scale, it can provide ad-hoc aggregate queries，clickhouse too；

They have similar disadvantages, such as slow data writing。

Which engine should I do with OLAP？

This is the great article https://leventov.medium.com/comparison-of-the-open-source-olap-systems-for-big-data-clickhouse-druid-and-pinot-8e042a5ed1c7

Either your organization should have engineers who are able to read, understand and modify the source code of the chosen system, and have capacity to do that. Note that ClickHouse is written in C++, Druid and Pinot — in Java.

No need to know Java or C++ - just use them.

I work in Altinity and my job is literally to read Clickhouse source code.

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
