! using indices improves search-perf, but degrades ins/upd perf
|
|
! indices have types
|
|
! 21:30 explain (analyze, costs off, buffers) -- buffers is aprox about num of disk ops
|
|
! b-tree index has nodes with like 100 children
|
|
! 26:00 index only scan
|
|
! Heap Fetches: 4 (pg went into table because of visibility/autovac)
|
|
! 28:00 index on random uuid - will have more r/w
|
|
! because of randomizeness (pg optimized insert of sequential values)
|
|
! !!! UUID v7 can generate sequential ones
|
|
! select ... from users where state = 'PENDING' and name = ?
|
|
! create index state_name_users on users(name) include(state) -- idx will not sort by state, just include it
|
|
! create index of (col1, col2) -- index sorted on combination of state, name
