Applying topological graph changes

One or more non-transitory computer-readable media storing a set of instructions, wherein the set of instructions includes instructions, which when executed by one or more hardware processors, cause:

• receiving a query having a particular data manipulation language (DML) instruction to execute at a database management system (DBMS), the particular DML instruction referencing a particular object change to a particular object stored in non-volatile memory at the DBMS;
• determining that the particular object change, indicated by the particular DML instruction, causes a graph change to an in-memory graph that is stored in volatile memory and is based, at least in part, on the particular object;
• wherein source and destination pair vertices of the in-memory graph are data elements related to one another by a data relationship of corresponding data items of one or more objects stored in the non-volatile memory at the DBMS;
• completing execution of the query, including executing the particular DML instruction, by a first set of processes, at least by:
• performing the particular object change to the particular object in the non-volatile memory without performing the graph change to the in-memory graph in the volatile memory, and
• generating and associating the particular object change with a graph change indication;
• in response to receiving a graph operation on the in-memory graph, performing, by a second set of processes, different from the first set of processes, the graph operation at least by:
• based at least in part on the graph change indication, determining that the graph change is to be performed for the in-memory graph in the volatile memory;
• performing one or more operations to reflect the graph change to the in-memory graph in the volatile memory.
