275558612,MDExOlB1bGxSZXF1ZXN0Mjc1NTU4NjEy,445,closed,0,"Extract facet code out into a new plugin hook, closes #427",9599,"Datasette previously only supported one type of faceting: exact column value counting.

With this change, faceting logic is extracted out into one or more separate classes which can implement other patterns of faceting - this is discussed in #427, but potential upcoming facet types include facet-by-date, facet-by-JSON-array, facet-by-many-2-many and more.

A new plugin hook, register_facet_classes, can be used by plugins to add in additional facet classes.

Each class must implement two methods: suggest(), which scans columns in the table to decide if they might be worth suggesting for faceting, and facet_results(), which executes the facet operation and returns results ready to be displayed in the UI.",2019-05-03T00:02:41Z,2019-05-03T18:17:18Z,2019-05-03T00:11:27Z,2019-05-03T00:11:27Z,ea66c45df96479ef66a89caa71fff1a97a862646,,,0,1b47d4d8736627c260eb4e8303e552b0e9620a01,efc93b8ab5a21e3802f75f08d5e41409f5684b5d,OWNER,107914493,https://github.com/simonw/datasette/pull/445,,
