Posted to the wrong alias. Just wonder if anyone else feels such a use case. Thanks. ---------- Forwarded message ---------- From: Sand Stone <sand.m.stone@xxxxxxxxx> Date: Sun, Feb 11, 2018 at 11:34 AM Subject: persistent read cache To: pgsql-hackers@xxxxxxxxxxxxxxxxxxxx Hi. I wonder if there is such a thing or extension in the PG world. Here is my use case. I am using PG (PG10 to be more specific) in a cloud VM environment. The tables are stored in RAID0 managed SSD backed attached storage. Depending on the VM I am using, I usually have 256GB local SSD unused. I wonder if PG could leverage this local SSD as a read (page/block) cache, to complement/extend the DRAM by used by shared_buffer today. Thanks.
