摘要： A database query comprising a logical table definition and at least one route tracing indicator is forwarded to at least one distributed database node within a distributed network of databases. At least one query response is received including distributed route tracing information associated with each distributed database node that processed the database query along a path associated with the at least one query response. The received distributed route tracing information is processed to characterize query route propagation within the distributed network of databases. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

摘要： A logical table definition is received as part of a database query within a distributed database system. A determination is made as to whether the received logical table definition matches a local logical table definition. The query is processed in response to determining that the received logical table definition matches the local logical table definition. The query is forwarded to at least one other distributed database node.

摘要： A database query is received that includes a logical query indicator at a distributed database node within a distributed network of databases. The logical query indicator includes at least one physical database query and at least one database node identifier that allows at least one distributed database node to identify at least one physical database to execute the physical database query against. It is determined that the at least one database node identifier matches a local node identifier. The at least one physical database query is executed against at least one local physical database table. A local query response is formed including data retrieved from the at least one local physical database table. The database query is responded to with at least the local query response. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
