Recently I published a blog on s3-select.

the Blog discusses what it is, and why it is required.

the last paragraph discusses the Trino(analytic SQL utility) and its integration with Ceph/s3select.

that integration is still on-work, and it is quite promising.

Trino does not just provides a comprehensive SQL but also provides scalable processing for the SQL statements.

we will be glad to hear your ideas and comments.

Gal.
