It's an adaptation of a feature table where the weight is the number of
occurrences found during ingest. The rowId's are features that are
relevant to my queries/row counts (e.g. timespan, geo-space, document
partition id, keywords, etc.)
ROWID FAM QUAL VIS VALUE
===== === ==== === ====White KEYWORD OTHER public 123
14SU GEO MGRS public 456
9223 TIMESPAN EPOC public 7890
DOCPART1 DOCUMENT PARTITION public 1234567
One tablet server will know how many rows exist across the cluster for
any ROWID. So I can quickly determine how many rows exist in all my
tablet servers with one simple scan.
Obviously you have counter them all on ingest and update the edge table.

Can you describe the Edge Table approach or provide a reference?
