OpenDAL supporting unified access to different databases？

[wking1986]

OpenDAL has considered supporting unified access to different databases, such as MySQL, PGSQL, and Oracle. This means that users can interact with different databases using a single interface, making it easier to switch between different database systems without changing the code.

Thanks for sharing the idea.

OpenDAL is engineered to access storage services such as S3 and HDFS. It does not aim to provide unified access to various databases.

While OpenDAL supports various databases such as PostgreSQL, we exclusively utilize the PostgreSQL table for key-value mapping and store data as a BLOB which means OpenDAL doesn't know about other fields inside this table.

In conclusion: OpenDAL doesn't intend to be another SQL ORM or queries builder.
