Abstract: Optimizing database table scans in presence of SMDO records is provided. An SMDO record corresponding to a most recent span of rows for a column associated with a query predicate is read. It is determined whether a condition for excluding a span of rows is true for the SMDO record based on a type of the query predicate. In response to determining that a condition for excluding a span of rows is not true for the SMDO record, the most recent span of rows is added to a list of spans of rows to scan. It is determined whether a condition for excluding all preceding spans of rows is true for the SMDO record based on the type of the query predicate. In response to determining that a condition for excluding all preceding spans of rows is true for the SMDO record, reading the set of SMDO records is stopped.

Abstract: The present invention provides a method, system and computer program product for replication control using eventually consistent meta-data. In an embodiment of the invention, a method for replication control using eventually consistent meta-data is provided. The method includes replicating data in a replication data processing system of nodes coupled to one another over a computer communications network. The method also includes replicating meta-data representing the state of the replication data processing system into a data structure of eventually consistent meta-data. Finally, the method includes managing the replication of the data according to the replicated meta-data.
