In a multitenant data platform architecture, one or more supporting data tables are used to efficiently retrieve data responsive to data retrieval requests. Programmatic code markers associated with contextual data about a data transaction thread are identified. The contextual data is examined using the one or more programmatic code markers invoked by the database in the data transaction thread at runtime. Based on the contextual data returning an indication of a data corruption in one or more supporting data structures, an action associated with the data transaction thread is performed. A log of data corruptions and corresponding call stack trace data may be generated. The data transaction thread may be allowed to continue to execute statements that modify data tables, or the data transaction thread may be terminated.
