Increasing efficiency to rate limiting

A server computer system providing rate limiting, the system comprising:

• a processor configured to:
• receive a request from a client via a network interface of the server;
• utilize an early stage process to search for a rate-limiting token bucket (TB) using first metadata associated with the request;
• responsive to finding the TB using the first metadata, perform a response operation;
• responsive to not finding the TB using the first metadata, utilize a late stage process to search for the rate-limiting TB using server-side session data associated with the request;
• responsive to not finding the TB using the session data:
• create the TB and associate with it at least two search indexes comprising the first metadata associated with the request and the session data;
• and
• perform the response operation;
• wherein the response operation comprises the processor being configured to transmit, via the network interface, a determined response to the client.

A computer program product comprising a computer readable storage medium having computer-readable program code embodied therewith to, when executed on a processor:

• receive a request from a client via a network interface of the server;
• utilize an early stage process to search for a rate-limiting token bucket (TB) using first metadata associated with the request;
• responsive to finding the TB using the first metadata, perform a response operation;
• responsive to not finding the TB using the first metadata, utilize a late stage process to search for the rate-limiting TB using server-side session data associated with the request;
• responsive to not finding the TB using the session data:
• create the TB and associating with it at least two search indexes comprising the first metadata associated with the request and the session data;
• and
• perform the response operation;
• wherein the response operation comprises the processor being configured to transmit, via the network interface, a determined response to the client.
