I have a pretty small table (~20MB) that is accessed very frequently and randomly, so I want to make sure it's 100% in memory all the time. There is a lot of other staff that's also gets accessed frequently, so I don't want to just hope that Linux file cache would do the right thing for me.
Is there any way to do that? One idea I have in my head is to start a process that does mmap() and mlock() with the table file. Will it work? If so, are there any potential problems? -- View this message in context: http://www.nabble.com/How-to-keep-a-table-in-memory--tf4789293.html#a13700771 Sent from the PostgreSQL - hackers mailing list archive at Nabble.com. ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
