UnverifiedDouble buffering refers to the same data page existing simultaneously in both the OS page cache and shared buffers, resulting in duplicated memory usage and dilution of effective cache capacity.65% similarUnverifiedDeepEP provides four types of buffers: EP Buffer (for expert-parallel Dispatch and Combine), PP Buffer (for pipeline-parallel Send/Receive), Ingram Buffer (for Table writes and per-layer Fetch), and Bucket Buffer (for bucketing operations)62% similarUnverifiedDisabling file caching eliminates double-caching waste, but once data misses shared buffers it goes directly to the storage layer, requiring a sufficiently high hit rate; otherwise the cost of a miss may be amplified.61% similarUnverifiedLakebase's local file cache is a layer of local SSD/memory cache situated between shared buffers and remote object storage within its cloud-native storage architecture, and is not the OS page cache of standard Postgres.60% similar
