System, method, and various embodiments for a resource efficient schema object creation system are described herein. An embodiment operates by receiving a schema-change request at a first node of a cluster of computing nodes. The first node creates and populates a schema object in a shared storage, based on the schema-change request. An entry is generated in a reverse transaction log, the entry corresponding to the schema object stored in the shared storage device. A coordinator node is configured to read the entry from the reverse transaction log, update a schema, and generate an entry in a forward transaction log. The first node executes the entry in the forward transaction log, wherein the executing comprises updating a catalog of the first node to include the schema object stored in the shared storage, wherein upon a completion of the updating, the schema object is accessible by the first node.

Resource efficient schema object creation system

A system includes detection of a first allocation of a first memory size in an object store for storage of a first logical page, in response to detection of the first allocation, incrementing a count associated with the first memory size by a first data structure associating a respective count with each of a plurality of memory sizes, detection of a first deallocation of the first logical page, in response to detection of the first deallocation, decrementing a count associated with a second one of the plurality of memory sizes by the first data structure, and determination of a memory usage associated with the object store based on the counts associated with each of the plurality of memory sizes by the first data structure wherein the second one of the plurality of memory sizes is different from the first memory size.

Database object store size estimation

Disclosed herein are various embodiments a code simplification system. An embodiment operates by determining that a software version of a coordinator node is different from a software version of one or more worker nodes, Commits by the one or more worker nodes to a database are disabled based on the determination that the software versions differ. An update is performed on each of the one or more worker nodes. An acknowledgement that the update on each of the one or more worker nodes has completed is received, and the commits to the database by the one or more worker nodes is enabled.
