20090083302 | USING AN INCREMENTING TIME ELEMENT TO SELECTIVELY ADD LIST ITEMS TO EITHER THE START OR THE END OF AN ORDERED LIST - The present invention discloses a solution for establishing position values of new items in an ordered list at either the start or the end of the list without using of markers and without needing to query all the items of the list. In the solution, a command to add a new item to the ordered list can be received, which specifies whether the item is to be added at the start or the end of the list. When the item is to be added to the end of a list, an item position value for a new item can be set equal to a current value of a time element. Otherwise, it can be set equal to negative one times the current value of the time element (assuming smallest to largest ordering). Mathematical derivates that produce the same effect are contemplated. | 03-26-2009 |
20120331085 | LOAD BALANCING BASED UPON DATA USAGE - 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. | 12-27-2012 |

20130046811 | STREAM PROCESSING USING A CLIENT-SERVER ARCHITECTURE - A method of responding to requests using stream processing can include receiving a server request from a server, wherein the server is configured to generate the server request responsive to a client request, and generating a request identifier associated with the server request. The method can include, responsive to the server request, sending a stream processing request derived from the server request to a first stream processing node. The stream processing request can include the request identifier. Responsive to receiving a create response message including a stream processing result and the request identifier from a second stream processing node, the stream processing result can be correlated with the server request. A write response message specifying the stream processing result can be sent to the server. | 02-21-2013 |
20130046859 | STREAM PROCESSING USING A CLIENT-SERVER ARCHITECTURE - A system for responding to requests using stream processing can include a processor configured to initiate executable operations including include receiving a server request from a server, wherein the server is configured to generate the server request responsive to a client request, generating a request identifier associated with the server request, and, responsive to the server request, sending a stream processing request derived from the server request to a first stream processing node. The stream processing request can include the request identifier. Responsive to receiving a create response message including a stream processing result and the request identifier from a second stream processing node, the stream processing result can be correlated with the server request. A write response message specifying the stream processing result can be sent to the server. | 02-21-2013 |
20140115043 | STREAM PROCESSING USING A CLIENT-SERVER ARCHITECTURE - 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. | 04-24-2014 |
20140115044 | STREAM PROCESSING USING A CLIENT-SERVER ARCHITECTURE - A system for responding to requests using stream processing comprises a computer readable storage medium having computer readable program code embodied therewith and a processor coupled to the computer readable storage medium. Responsive to a client request, a processing thread is assigned for handling the client request. A return connection is established within the processing thread. A server request derived from the client request to a stream server configured to interact with a plurality of stream processing nodes is sent, and the server request comprises 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 is returned to an active state. | 04-24-2014 |
20140115045 | STREAM PROCESSING USING A CLIENT-SERVER ARCHITECTURE - 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. | 04-24-2014 |
20140115046 | STREAM PROCESSING USING A CLIENT-SERVER ARCHITECTURE - 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. | 04-24-2014 |
