Abstract: Techniques discussed herein relate to an object-relational database management system (ODMS) (e.g., a PostgreSQL ODMS) that provides in-line materialization of database pages corresponding to read requests. A replica node of the ODMS may be configured to share access to a shared block storage volume with a primary node. The replica node may receive log updates from the primary indicating changes to the object-relational database. The read replica, in response to receiving a read request, may update a previous version of a database page, store the database page in local memory, and replay the log updates to update the database page in local memory. Data may be provided from the updated database page in response to the read request.

Abstract: Techniques discussed herein relate to an object-relational database management system (ODMS) (e.g., a PostgreSQL ODMS) that utilizes a shared block storage volume (SBSV) for storage. The SBSV may utilize a file system that enables a single-writer-multiple reader model in which a primary computing node may read or write to the SBSV and one or more replica computing nodes are restricted from writing to the SBSV. To enable the primary computing node to write data at its own pace, regardless of the status of synchronization at each of the one or more replica computing nodes, the SBSV may include a staging area that maintains data that has not yet been updated at one or more of the replica computing nodes. When the primary computing node no longer maintains the data in local memory, the one or more replica computing nodes may obtain the data from the staging area of the SBSV.
