i have tricky problem trying find efficient way of ordering set of objects (~1000 rows) contain large (~5 million) number of indexed data points. in case need query allows me order table specific datapoint. each datapoint 16-bit unsigned integer. i solving problem using large array: object table: id serial not null, category_id integer, description text, name character varying(255), created_at timestamp without time zone not null, updated_at timestamp without time zone not null, data integer[], gist index: create index object_rdtree_idx on object using gist (data gist__intbig_ops) this index not being used when select query, , not anyway. each day array field updated new set of ~5 million values i have webserver needs list objects ordered value of particular data point: example query: select name, data[3916863] weight object order weight desc currently, takes 2.5 seconds perform query. question: there better approach? happy insertion
