High-performance database replication systems and methods

A system for performing database replication, the system comprising:

• at least one memory for storing computer-executable instructions;
• and
• at least one processor for executing the instructions stored on the at least one memory, wherein execution of the instructions programs the at least one processor to perform operations comprising:
• generating, at a producer cluster, a binary change log based on a write transaction made to a database partition in the producer cluster;
• including with the binary change log a sequence number corresponding to the write transaction;
• transmitting the binary change log from the producer cluster to a consumer cluster;
• determining, at the consumer cluster, whether to apply the binary change log based on the sequence number included with the binary change log;
• applying the binary change log to a database partition in the consumer cluster;
• and
• storing, at the consumer cluster, the sequence number by combining the sequence number with a numerical range comprising a first number and a second number, the second number comprising a value corresponding to a most recent binary change log applied to the database partition in the consumer cluster, wherein combining the sequence number with the numerical range comprises:
• determining that the sequence number consecutively follows the second number, and replacing the second number with the sequence number;
• or
• determining that the sequence number does not consecutively follow the second number, and storing at the consumer cluster a second numerical range comprising the sequence number.
