We publish multiple middlewares to allow a local_date join process. All this middlewares receives 4 arguments as input from ctx.state:

current: Array with data grouped by date
comp: Array with comparable data grouped by date
filters.comparableDate.data: Array with local_date and comparable date associations, like: { local_date: '2019-11-12', comparable_commercial: '2018-11-13', comparable_calendar: '2018-11-12' }
compType: String with comprable type commercial | calendar | custom

There are two types of middlewares, comparableJoin and comparableA2Join, and each of them have 3 subtypes of middlewars:

comparableJoin | comparableA2Join: Joins in dates from filters.comparableDate.data the data from current and comp. So return data will have all possible dates.
comparableLeftJoin | comparableA2LeftJoin: This middleware uses left join strategy, so as the left part of the join is current data, return will have all dates from left side, joined with mathes from comp (right side) using filter.comparableDate.data associations.
comaprableRightJoin | comparableA2RightJoin: This middleware uses right join strategy, so return will have all comp data joined with current data matches using filter.comparableDate.data associations.
