i have crated new database scratch , loaded there 1 single type of node. there no relationships. each node has 2 properties. these properties values not null. here math cannot understand in webadmin dashboard. nodes: 19 798 966 properties: 25 440 880 relationships: 0 relationship types :0 i expecting number of properties 19 798 966 x 2 = 39 597 932 however when query database, results are: $ match (n) has(n.woka_id) return count (n); count (n) 19 798 966 and $match (n) has(n.woka_title) return count (n); count (n) 19798966 what wrong here? webadmin doesn't report counts, indeed highest id in use reported. since multiple properties stored internally in same block you'll see misleading numbers there. validate: match (n) has(n.woka_title) , has (n.woka_id) return count(n) == 19798966 should return true .
