Change Details

@jcrespo indicated this should be fine, as long as it doesn't require new hardware, which it does not (that would require more discussion). We don't require separate physical hardware (where to put it is a decision for ops). The first statement of https://gerrit.wikimedia.org/r/#/c/223724/1/puppet/modules/role/templates/externalstore/conf.php.erb indicates basically what is needed to set up a new logical cluster (except it would have some Flow-specific name on the first line). To research before Tuesday: Rows/size needed for Flow (number of distinct rev_content and rev_content_length should approximate this). Assigning to myself temporarily for that.
