stampede

It was both. There were two separate software based on the same underlying technology: * ToroDB Stampede[1]: MongoDB replica, converting on-the-fly documents to relational structures. Targeting OLAP, as data normalization made queries from some % faster to 2-3 orders of magnitude faster. * ToroDB Server[2]: what DocumentDB is or FerretDB is planning to be. It was less developed than Stampede, certainly. [1]: https://github.com/torodb/stampede/ [2]: https://github.com/torodb/server (edit: formatting)

Yes, it's possible to have Wekan Meteor.js <=> MongoDB <=> ToroDB => PosgreSQL or MySQL read-only mirroring, for reporting etc if needed https://github.com/wekan/wekan-postgresql https://github.com/torodb/stampede/issues/203

Hi, I'm current maintainer of Wekan. Wekan can be used locally on local network that is not connected to Internet. There is no offline sync yet. Wekan is made with Meteor.js Javascript framework, using Node.js and MongoDB as backend currently. There is possibility to use read-only mirroring to PostgreSQL using ToroDB: https://github.com/wekan/wekan-postgresql but currently there's this bug, please wait for it to be fixed: https://github.com/torodb/stampede/issues/202 There is issue about directly using other backends than MongoDB, but that would require some code changes, so it's not implemented yet: https://github.com/wekan/wekan/issues/787 Wekan can be installed on x64 operating systems where source/Docker/Ubuntu snap/VirtualBox installs work. https://github.com/wekan/wekan/wiki/Platforms There is no Raspberry Pi version yet: https://gi
