Parallel database mirroring

A system comprising:

• a first node hosting a primary database;
• a second node hosting a mirror database;
• a master node connected with the first node and the second node through a network;
• and
• a non-transitory storage device storing instructions that, when executed, cause at least one of the first node, second node, or master node to perform operations comprising:
• determining, by the master node based on one or more data records stored in a master node database, that the primary database is synchronized with the mirror database;
• and
• in response to the determining that the primary and mirror databases are synchronized:
• writing, by a first process, a database page to the primary database and to the mirror database asynchronously and substantially in parallel, the database page containing data changes resulting from a transaction;
• and
• writing, by a second process, transaction logs to the mirror database asynchronously and substantially in parallel with writing the transaction logs to the primary database, wherein writing the database page by the first process to the mirror database is independent of writing the transaction logs by the second process to the mirror database,
• wherein writing the database page to the mirror database is not based on the transaction logs, and
• wherein each of the first node, second node, and master node includes one or more computers comprising one or more hardware processors.

A non-transitory storage device storing instructions that, when executed, cause one or more processors to perform operations comprising:

• determining, by a master node of a computer network and based on one or more data records stored in a master node database, that a primary database hosted on a first node of the computer network is synchronized with a mirror database hosted on a second node of the computer network;
• and
• in response to the determining that the primary and mirror databases are synchronized:
• writing, by a first process, a database page to the primary database and to the mirror database asynchronously and substantially in parallel, the database page containing data changes resulting from a transaction;
• and
• writing, by a second process, transaction logs to the mirror database asynchronously and substantially in parallel with writing the transaction logs to the primary database, wherein writing the database page by the first process to the mirror database is independent of writing the transaction logs by the second process to the mirror database,
• wherein writing the database page to the mirror database is not based on the transaction logs, and
• wherein each of the first node, second node, and master node includes one or more computers comprising one or more hardware processors.
