Distributed storage processing statement interception and modification
First Claim
1. A non-transitory computer readable storage medium with instructions executed by a processor to:
- intercept a query statement at a master machine or a machine delegated to receive query statements sent to the master machine, wherein the query statement is a distributed storage and distributed processing statement from a client machine;
evaluate tokens associated with the query statement to selectively identify a pattern match, wherein the tokens are evaluated to selectively identify a pattern match of connection pattern tokens, login pattern tokens and query pattern tokens; and
form altered tokens for the query statement in response to the pattern match to form a revised query statement, wherein the revised query statement is produced in response to application of a policy rule, wherein the revised query statement maintains computation, logic and procedure of the query statement, but alters parameters of the query statement as specified by the policy rule.

Abstract
A non-transitory computer readable storage medium has instructions executed by a processor to intercept a query statement at a master machine. The query statement is an instruction from a client machine that specifies how data managed by a distributed storage system should be processed and provided back to the client. In the communication between the client and the master machine, tokens associated with the statement are evaluated to selectively identify a pattern match of one of connection pattern tokens, login pattern tokens or query pattern tokens. For the query pattern tokens, altered tokens for the query statement are formed in response to the pattern match to establish a revised statement. The revised statement is produced in response to application of a policy rule. The revised statement maintains computation, logic and procedure of the statement, but alters parameters of the statement as specified by the policy rule.
