Abstract
The disclosure is directed to storing a data log file ('log') in a distributed computing system. The log can be stored as a sequence of data records ('records'). A number of writer computers (“writers”) can write to a log, and a number of reader computers (“readers”) can read from the log. A log sequencer computer (“log sequencer”) facilitates storage of the records in data storage nodes of the distributed computing system. When the log sequencer receives a request for appending a record to a log, the log sequencer assigns a sequence number to the record that is unique and increases monotonically within the log. When a reader requests the log, the records can be delivered to the reader in the order of their sequence numbers. Further, since the records are associated with sequence numbers, a reader can seek to arbitrary sequence number within the log.
