Updating a Multi-Tenant Database Concurrent with Tenant Cloning

A non-transitory computer readable medium having program instructions stored thereon that are capable of causing a computing system to implement operations comprising:

• receive a request to perform an update on tenants of a multi-tenant database;
• and
• perform the update, using an update process, on the tenants of the multi-tenant database, wherein performing the update includes:
• acquiring a lock, by the update process, to inhibit any tenant of the database from duplicating their respective data;
• accessing, using the update process, a list of entries in the database, wherein each of the entries corresponds to a tenant of the database;
• releasing the lock subsequent to completing the accessing;
• and
• permitting a clone process to create a clone of a tenant's data within the database concurrent with the update process performing the update.

A method comprising:

• receiving, at a computer system, a request to perform an operation on a multi-tenant database that includes updating database entries for a plurality of database tenants;
• performing the operation on the multi-tenant database, wherein performing the operation includes:
• accessing, by a process associated with the operation, a list of tenants in the database, wherein accessing includes using a lock to inhibit any tenant of the multi-tenant database from duplicating their respective data;
• releasing the lock in response to the process completing access to the list, wherein a duplication process is permitted acquire the lock and duplicate a tenant's data within the database subsequent to releasing the lock;
• performing the operation on tenants in the list;
• re-acquiring the lock by the process in response to performing the operation on tenants in the list;
• determining, in response to re-acquiring the lock, if any duplicate tenants have been created by the duplication process;
• and
• performing the operation on any duplicate tenants.
