Setting up Postgres with 128 tables of 1000 columns each, I measure the following times to fetch the columns info: ``` ======== Baseline ======== Min: 0.1101293980027549 Mean: 0.116194007100421 Median: 0.11580873148341198 ======== No fetch ======== Min: 0.011137755995150656 Mean: 0.012267920252634212 Median: 0.012091688506188802 ======== Proposed ======== Min: 0.13142116999370046 Mean: 0.1360591922988533 Median: 0.13438900698383804 ======== Proposed (vaefremov95) ======== Min: 0.12212352099595591 Mean: 0.12737997300137066 Median: 0.12580044448259287 ``` It seems the current query performs best. Possibly this changes when there are more tables. -- This is an automated message from the Apache Git Service.
