Transactional update system and method

A computer program product residing on a non-transitory computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:

• receiving a plurality of updates to one or more metadata pages of a storage system, wherein the plurality of updates include one or more bulk updates and one or more delta updates to the one or more metadata pages;
• defining a transaction record for the plurality of updates to the one or more metadata pages;
• writing the one or more delta updates to a non-volatile log;
• writing the one or more bulk updates of the plurality of updates to the one or more metadata pages of a first metadata store position;
• writing the one or more bulk updates the plurality of updates to the one or more metadata pages of a second metadata store position in response to writing the one or more bulk updates the plurality of updates to the one or more metadata pages of the first metadata store position;
• and
• setting a status indicator for the transaction record for the plurality of updates based upon, at least in part, writing the one or more delta updates to the non-volatile log and one or more of writing the one or more bulk updates the plurality of updates to the one or more metadata pages of the first metadata store position and writing the one or more bulk updates the plurality of updates to the one or more metadata pages of the second metadata store position.

A computing system comprising:

• a memory;
• and
• a processor configured to receive a plurality of updates to one or more metadata pages of a storage system, wherein the plurality of updates include one or more bulk updates and one or more delta updates to the one or more metadata pages, wherein the processor is further configured to define a transaction record for the plurality of updates to the one or more metadata pages, wherein the processor is further configured to write the one or more delta updates to a non-volatile log, wherein the processor is further configured to write at least a portion of the plurality of updates to the one or more metadata pages of a first metadata store position, wherein the processor is further configured to write the one or more bulk updates the plurality of updates to the one or more metadata pages of a second metadata store position in response to writing the one or more bulk updates the plurality of updates to the one or more metadata pages of the first metadata store position, and wherein the processor is further configured to set a status indicator for the transaction record for the plurality of updates based upon, at least in part, writing the one or more delta updates to the non-volatile log and one or more of writing the one or more bulk updates the plurality of updates to the one or more metadata pages of the first metadata store position and writing the one or more bulk updates the plurality of updates to the one or more metadata pages of the second metadata store position.
