Abstract: Responsive to a client request, a processing thread for handling the client request is assigned. Responsive to the client request, a server request is sent to a stream server configured to interact with a plurality of stream processing nodes. The processing thread is maintained in an idle state pending a write response message from the stream server. The processing thread is returned to an active state responsive to receiving the write response message including a stream processing result from the stream server. A client response including the stream processing result is sent to the client.

Abstract: A method of responding to requests using stream processing includes, responsive to a client request, assigning a processing thread for handling the client request. A return connection is established within the processing thread. A server request derived from the client request is sent to a stream server configured to interact with a plurality of stream processing nodes. The server request includes a thread identifier specifying the processing thread. The processing thread for handling the client request is maintained in an idle state pending a write response message from the stream server. Responsive to receiving the write response message comprising a stream processing result and the thread identifier from the stream server, the processing thread specified by the thread identifier is returned to an active state using a processor. A client response comprising the stream processing result is returned to the client over the return connection.

Abstract: A computer hardware system configured to respond to requests using stream processing includes a HTTP stream server including at least one processor. The at least one processor is configured to initiate and/or perform the following. Responsive to a server request received from a server, a stream processing request is sent to a first stream processing node. Responsive to a create response message received from a second stream processing node, a stream processing result is correlated with the server request. A write response message including the stream processing result is sent to the server. The stream processing request is derived from the server request and includes a request identifier associated with the server request. The create response message includes the stream processing result and the request identifier.

Abstract: A method for responding to requests using stream processing includes, responsive to a server request received from a server, a stream processing request being sent to a first stream processing node. Responsive to a create response message received from a second stream processing node, a stream processing result is correlated with the server request. A write response message including the stream processing result is sent to the server. The stream processing request is derived from the server request and includes a request identifier associated with the server request. The create response message includes the stream processing result and the request identifier.

Abstract: A method of load balancing can include segmenting data from a plurality of servers into usage patterns determined from accesses to the data. Items of the data can be cached in one or more servers of the plurality of servers according to the usage patterns. Each of the plurality of servers can be designated to cache items of the data of a particular usage pattern. A reference to an item of the data cached in one of the plurality of servers can be updated to specify the server of the plurality of servers within which the item is cached.

Abstract: Embodiments of the present invention provide a method, system and computer program product for page request management for aggregated page content. In an embodiment of the invention, a method for page request management for aggregated page content can include issuing on behalf of a user a request for dynamically aggregated components in a page. The method further can include inserting into a header of the request a key computed as a combination of identifiers for the aggregated components and last modified data for the aggregated components. Finally, the method can include receiving in response to the request a new page of dynamically aggregated components for the user only if the computed key does not match a key computed for the new page. Otherwise, only a response is received indicating that the page has not been modified.
