Thanks for your reply. Currently we have implement a sub-set of the ISO/GQL draft with some our
extension. It is widely used in the AntGroup. And the project is also released as an open source
project: https://github.com/TuGraph-family/tugraph-analytics.I'm going to investigate the way Babel
parser and the calcite adapter work and choose a better contribution
way.Thanks.2023年6月20日下午6:40，Stamatis Zampetakis <[email protected]> 写道：Hello,We definitely
welcome contributions that could improve the graph querycapabilities in Calcite. If something is part
of the SQL standard thenit can be contributed to the core SQL parser of Calcite. If it is notstandard
but still widely accepted/used it should probably land in thebabel parser. In every other case, we
have the adapters and we canaccept new ones if necessary.In general smaller contributions are easier
to review and merge so ifyou can divide your work into smaller parts and create JIRA ticketsfor each
we can reason about them individually.Other than that the following threads/topics may be somewhat

http://peter.eisentraut.org/blog/2023/04/04/sql-2023-is-finished-here-is-whats-newwhich we can
combine the graph query "Match" statement with the sql.And also the ISO/GQL have proposed
the GQL query. We have implement the SQL extend which can combine SQL with the ISO/GQL query in our
open source stream graph engine
TuGraph-Analytics(https://github.com/TuGraph-family/tugraph-analytics) based on calcite which can
combine the SQL process with the graph query in one streaming engine. We can see the syntax here:
https://github.com/TuGraph-family/tugraph-analytics/blob/master/docs/docs-en/application-development/dsl/overview.mdSo
I would like to know if the Calcite community plans to support graph query language in the future.
If possible, we would like to contribute our graph query extension to the community.Thanks.
