Abstract
Example implementations disclosed herein include techniques for a ready only bufferpool for use in local nodes of a multi-node computing system. Read only transactions executed by a processor can reference a ready only bufferpool resident in a VRAM on the same node. If the desired data page is in the bufferpool the transaction can immediately read data records from the cached data pages. If the desired data page is not in the bufferpool, then the transaction can cause a copy of a corresponding data page in a secondary memory to be installed in the bufferpool. The bufferpool can include more than one copy of a data page simultaneously to handle and prevent cache line misses. Data page are dropped from the bufferpool based on an incrementing per data page counter.
