Determining system information based on object mutation events

A non-transitory computer readable medium comprising instructions which, when executed by one or more hardware processors, causes performance of operations comprising:

• receiving a request to transmit a set of system updates for updating system information, wherein the set of system updates is associated with a particular identifier corresponding to a last-published event of a set of events used to determine the set of system updates;
• determining whether any of previously transmitted sets of system updates was associated with the particular identifier;
• responsive to determining that none of the previously transmitted sets of system updates were associated with the particular identifier, transmitting the set of system updates for updating the system information;
• and
• responsive to determining that one of the previously transmitted sets of system updates were associated with the particular identifier, refraining from transmitting the set of system updates for updating the system information.

A method comprising:

• executing a first retrieving operation to retrieve events from an event stream, wherein executing the first retrieving operation comprises retrieving a first set of events from the event stream, the first set of events comprising a particular event in the event stream and events subsequent to the particular event in the event stream;
• determining a first set of system updates corresponding to the first set of events;
• transmitting the first set of system updates corresponding to the first set of events;
• responsive to determining that an acknowledgement, corresponding to the transmission of the first set of system updates, has not been received, performing at least operations (a)-(d):
• (a) executing a second retrieving operation to retrieve events from the event stream, wherein executing the second retrieving operation comprises retrieving a second set of events from the event stream, the second set of events comprising (a) the first set of events and (b) one or more additional events not included in the first set of events;
• (b) trimming the second set of events, by removing the one or more additional events from the second set of events, to obtain the previously retrieved first set of events;
• (c) re-determining the first set of system updates corresponding to the first set of events;
• (d) re-transmitting the first set of system updates corresponding to the first set of events;
• receiving an acknowledgement corresponding to the re-transmission of the first set of system updates;
• wherein the method is executed by at least one device including a hardware processor.
