Abstract: A system to automatically increment read-watermarks based on a set of predefined rules and criteria and configured to perform operations that include: accessing a message thread that comprises a plurality of messages; detecting a display of a message from among the plurality of messages at a client device, the message corresponding with an identification number from among a plurality of sequentially assigned identification numbers associated with the plurality of messages; applying the identification number that corresponds with the message from among the plurality of messages to a data object within a database associated with the message thread; the data object indicating a most recent message read by a user of the client device based on the identification number; detecting a trigger event; and automatically incrementing the identification number associated with the data object within the database responsive to the trigger event.

Abstract: Methods, systems, and computer readable medium are provided for receiving an event message in a plurality of event messages, the event message comprising a sequence number and associated data, identifying the event message as an out-of-order event message based on the sequence number, assigning a priority level to the out-of-order event message based on a plurality of priority rules, and placing the out-of-order event message in a primary queue of messages based on the priority level assigned to the event message.
