A history table is generated that includes a main table part that represents the most recent version of the data record after the data record is updated, and a history table part that represents one or more past versions of the data record before the data record is updated. The history table is stored in the main memory of the server computer. | 12-06-2012 |
20130159265 | Parallel Uniqueness Checks for Partitioned Tables - An insertion of a record into a table that includes a primary key column and a second column that includes a global uniqueness constraint across all of a plurality of data partitions across which the table is split is initiated without checking that a value of the record in the second column is globally unique by contacting other partitions the one partition to which the record is to be added to. The insertion can be processed, at least in part by implementing a write lock on the one partition but without implementing a read lock on the other partitions. The write lock on the one partition can be released after the insertion is completed, after which the validity of the insertion can be verified, for example by examining the other parts and a delta partition corresponding to the table. The insertion can be undone if the insertion was not valid. | 06-20-2013 |
20130226869 | SELECTION OF ROWS AND VALUES FROM INDEXES WITH UPDATES - Methods and apparatus, including computer program products, for selection of rows and values from indexes with updates. In general, rows of an index may be associated with validity flags that indicate whether a row has been updated with an update inserted in a delta index; one scheme for value identifiers may be used for an index and another scheme for one or more delta indexes where all of the indexes are, to at least some extent, compressed according to dictionary-based compression; and multiple delta indexes may be used in alternation such that one delta index may accept updates while another is being updated. The delta indexes may also have validity flags and all updates, such as modifications of values, deletion of records, and inserting of new records may be handled as updates accepted by one or more delta indexes. | 08-29-2013 |
20140289285 | Equi-Joins Between Split Tables - A join operation between split data tables includes providing reduction data from first partitions to each partition among second partitions. The reduction data serves to identify actual values in one of the second partitions that also occur in one of the first partitions. Global IDs are assigned. Translation lists including the global IDs are sent to the first partitions. Each first partition and each second partition create globalized lists which can then be combined to generate respective first and second compiled lists. The join operation can then be conducted on the first and second compiled lists. | 09-25-2014 |
