How to let plywood use listFiltering?

Hi!

Druid have listFiltered filtering.

Ex)
{
    "type": "listFiltered",
    "delegate": {
       "type": "default",
       "dimension": "tags",
       "outputName": "tags"
    },
    "values": ["t3"]
}

Effect of that is similar to that of SQL HAVING ... clause.

I already checked https://plywood.imply.io/expressions, but I couldn't found any clues.

Would you please to help me with that?

Thanks.

A listFiltered spec is just a filter after the split (like a SQL HAVING filter) it will be used automatically if the conditions are right.

See:

plywood/test/simulate/simulateDruid.mocha.js
