integrating standalone database 'engine' into olap db
- Integrating a standalone database 'engine' into an OLAP database
i'm trying to build a proper understanding of what olap datastore vs olap data engine is. I tend to put too much value to keywords like "engine" vs "data store". If it has engine - I think it should be plugable into another tech stack.I found [this data tech](https://alirezasadeghi1.medium.com/open-source-data-engineering-landscape-2024-8a56d23b7fdb) landscape image.In the upper corner there is 2 categories - columnar olap database and olap engine.My background is in data engineering, so i automatically assume if a technology has 'engine' keyword - then it can be used as part of bigger olap db, because 'engine' means a smaller component.E.g. plugging engine pinot/druid as part of proper olap db - apache kudu.1.Is this assumption correct?2.what is the difference between olap database and olap engine?

- I found a [data engineering tech landscape chart on Medium](https://alirezasadeghi1.medium.com/open-source-data-engineering-landscape-2024-8a56d23b7fdb) with two OLAP categories in the top-right corner:
- | Columnar OLAP Database | Real-Time OLAP Engine |
- |------------------------|-----------------------|
- | Apache Kudu | ClickHouse |
- | Greenplum Database | Pinot |
- | MonetDB | Druid |
- | DuckDB | Apache Kylin |
- | Databend | Doris |
- | ByConity | StarRocks |
- | Hydra |
- My background is in data engineering, so I automatically assume if a technology has the 'engine' keyword, then it can be used as part of bigger OLAP database, because 'engine' means a smaller component.
- E.g. plugging engine Pinot or Druid as part of proper OLAP database like Apache Kudu.
- 1. Is this assumption correct?
- 2. What is the difference between an OLAP database and an OLAP engine?
