Implementations store an event associated with a topic in a database to allow for the event to be transmitted in order with respect to other events associated with the topic which are stored in the database. A commit of a transaction is performed that includes inserting the event's payload in a record in a database object. After the commit, a field for the record is updated with an identifier of the commit. The identifier and identifiers of other commits of other transactions on the database indicate ordering of the commit with respect to the other commits. Another field of another record is updated based on the identifier and a last stored value such that the payloads of the event and of the other events are retrievable to be transmitted in an order based on the value of the other field and values of other fields of other records.
