Lava Satellite Server

The Satellite Server is a special version of the Lava Primary Server, targeted at providing remote client support in an extended Distributed SQL network.

a Satellite Server is appropriate where one or more users connect to a remote Lava Primary Server and the link bandwidth is compromised (between 500 Kbps and 5 Mbps) which would result in lengthy connect delays and slow application response - especially where this bandwidth is shared between several users.

In such cases, a Satellite Server may be configured at the remote site and connected to the Primary Server. A broader set of schemas and tables are typically distribued to the Satellite Server, in order to cover all data requirements for the users linking to the database.

Once the Satellite Server has connected to the Primary Server and data distribution has concluded, local users connect directly to the Satellite Server. Connect time and application response are enhanced to levels close to that of a local connection to the Primary Server.

The Satellite Server acts as a large, intelligent buffer - collecting data updates from local users and transmitting them to the Primary Server, as well as receiving updates from the Primary Server and re-distributing them to all local users. Combined with the local buffering of large distribution datasets, this serves to reduce the data transmission to and from the Primary Server to the minimum possible.
