Gateway apparatus and method for dynamically applying API settings

A gateway apparatus comprising:

• at least one processor;
• a memory coupled to the at least one processor;
• and
• a setting unit implemented in the memory, the setting unit comprising a first rule table and a second rule table to store a set value for processing an API (application programming interface) request, and a reference flag,
• wherein the memory stores program commands that, when executed by the at least one processor, cause the gateway apparatus to implement:
• a sub-processing unit that processes the API request of a client terminal based on API settings through a plurality of sub-threads;
• and
• a main processing unit that updates new API settings in a rule table other than a rule table corresponding to a reference value of the reference flag through a main thread when receiving the new API settings, and sets the reference value of the reference flag to a reference value corresponding to the updated rule table when the update is completed,
• wherein the first rule table stores the API settings for processing the API request,
• wherein the second rule table stores API settings different from those of the first rule table, and
• wherein the reference flag sets a reference value indicating which rule table, among the first rule table and the second rule table, in which the API settings to be referenced by the plurality of sub-threads so as to process the API request at a current time are stored.

An API (application programming interface) setting system comprising:

• at least one gateway apparatus mediating a communication linkage between a plurality of client terminals and a plurality of target servers, and managing API settings for processing an API request;
• and
• an API manager device providing the API settings to the gateway apparatus at a preset period,
• wherein the gateway apparatus comprises:
• at least one processor;
• a memory coupled to the at least one processor;
• and
• a setting unit implemented in the memory, the setting unit comprising a first rule table and a second rule table to store a set value for processing the API request, and a reference flag,
• wherein the memory stores program commands that, when executed by the at least one processor, cause the gateway apparatus to implement:
• a sub-processing unit that processes the API request of a client terminal based on API settings through a plurality of sub-threads;
• a main processing unit that updates new API settings in a rule table other than a rule table corresponding to a reference value of the reference flag through a main thread when receiving the new API settings, and sets the reference value of the reference flag to a reference value corresponding to the updated rule table when the update is completed,
• wherein the first rule table stores the API settings for processing the API request,
• wherein the second rule table stores API settings different from those of the first rule table, and
• wherein the reference flag sets a reference value indicating which rule table, among the first rule table and the second rule table, in which the API settings to be referenced by the plurality of sub-threads so as to process the API request at a current time are stored.
