Abstract:
Embodiments of the present invention provide a column-oriented database processing method, where a column-oriented database includes a marker column and more than one data column, the data column is used to store specific data in a column store manner, a value of a marker bit of each row in the marker column is used to indicate validity of data that is located in a same row as the marker bit, and the method includes: receiving a query request sent by an application program, where the query request contains a query condition; querying the more than one data column according to the marker column and the query condition to obtain a query result that meets both the query condition and a requirement that a marker bit of the query result in the marker column is valid; and sending the query result to the application program.
Abstract:
A server invocation method includes a proxy server sending a first subscription message to a second server registration center based on configuration information, where the first subscription message is used to subscribe to information about at least one invoked second server. The proxy server receives a response message sent by the second server registration center and registers the information about the at least one invoked second server with the first server registration center, so that the at least one first server invokes the at least one second server.
