Abstract: A method includes receiving data in a first format to be written into a data storage, where the first format is a multiversion concurrency control (MVCC) row format. The data is stored in the first format in the data storage and is transitioned from the first format to a second format based on a first transition parameter, where the second format is an MVCC columnar format. Data is stored in the second format in the data storage and is transitioned from the second format to a third format based on a second transition parameter, where the third format is a columnar format. The data storage stores non-overlapping data in the first format, the second format, and the third format.

Abstract: A method and apparatus that includes processing for providing distributed communication routing that, in one embodiment, begins by obtaining registration information from a plurality of forwarding engines, for identifying the plurality of forwarding engines based on the registration information, for generating at least one specific forwarding table for at least one corresponding forwarding engine of the plurality of forwarding engines, and for forwarding the specific forwarding table to the corresponding forwarding engine. In an alternate embodiment, the processing determines internal routing connections and external routing connections for the plurality of forwarding engines after identifying the forwarding engines, generates at least one external forwarding table for at least some of the plurality of forwarding engines, and generates at least one specific internal forwarding table for a corresponding forwarding engine. The tables are forwarded to the corresponding forwarding engine or engines.

Abstract: A configuration server is incorporated into a distributed router to support multiple route servers in an internetworking system. The multiple route servers in the system provide load sharing and/or standby functionality. In the system route servers provide routing decisions while edge forwarders are the packet forwarding elements. The configuration server is responsible for mapping edge forwarders to route servers.
