Hypertable doesn't support the traditional notion of "update". It keeps historical time series revisions of each record. To "update" a record in hypertable, you insert a newer (more recent) version of the record. When you select that record, you will get that record along with all of the older versions. To restrict the number of versions of a record (or cell) that Hypertable keeps, look at the MAX_VERSIONS clause of the column specifier in the CREATE TABLE command. - Doug --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Hypertable Development" group.
