OK. one more thought :) A while ago, I did find ArangoDB [1]. They say: "You can run ArangoDB 1.4 on a Raspberry PI." which is quite cool. ... I think it will show 100% CPU load, if you really throw your data at it, but this would be worth a try :))) ArangoDB is available for many Operating systems and has a HTTP API ... no LAMP stack :) >From there site: An open-source database with a flexible data model for > documents, > graphs, > and key-values. > > Build high performance applications using a > convenient sql-like query language or JavaScript extensions. > Having a look at there performance tests [2] they should be able to receive data quite fast. If they can handle 150 mio documents could be tested :) How fast you can delete the stuff ? ... I don't know :) But the cool part here is: they can handle key-value stores and graphs. So if you design your indexes and graph connections right, imo it should be possible, to filter out data in portions, that could be handled by TW. So the initial TW would be empty. Then it loads eg the root / first / and second level of your pre-populated tree. Depending on the user actions. You could go down the tree, and pre-fetch the next level of the relevant data only. just some ideas have fun! mario [1] http://arangodb.org/ [2] https://www.arangodb.org/2013/11/22/measuring-arangodb-insert-performance -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
