Consistent read queries from a secondary compute node

A method of data access, comprising:

• submitting a request for a page of data to a storage node in response to a read request, wherein the request includes a first log sequence number that indicates an update state of a local store of a compute node;
• receiving, from the storage node in response to the request, the page of data and a second log sequence number that indicates an update state of the page;
• waiting until the first log sequence number is greater than or equal to the second log sequence number, wherein the first log sequence number is updated in response to automatic updates of the local store of the compute node;
• retrieving a row of data from the page in accordance with the read request;
• and
• returning a response to the read request based on the row of data.

A data access method, comprising:

• submitting a request for a page of data to a storage node in response to a read request, wherein the request comprises a page identifier and a first log sequence number that specifies latest update state of a local store of secondary compute node, that processes read queries, in terms of application of transaction log records;
• receiving, from the storage node in response to the request, the page of data and a second log sequence number that indicates an update state of the page of data in terms of application of the transaction log records;
• waiting until the first log sequence number is greater than or equal to the second log sequence number, wherein the first log sequence number is updated in response to automatic application of the transaction log records to the local store;
• retrieving a row of data from the page of data in accordance with the read request;
• and
• returning a response to the read request based on the row of data.
