Abstract: Provisioning timestamp-based storage units for time series data is described. A time series database system determines a remaining time period for a first storage unit to reach a storage capacity, the first storage unit storing first data with a first minimum timestamp. The time series database system provisions a second storage unit if the remaining time period for the first storage unit satisfies the provisioning threshold and stores second data with a second minimum timestamp to the second storage unit. The time series database system dispatches a query for third time series data to any storage unit if a time span from a minimum timestamp to a maximum timestamp associated with the storage unit includes at least part of a time range associated with the third time series data. The time series database system responds to the query for the third time series data based on dispatching the query.

Abstract: Information from multiple databases is retrieved and stored on a database storage system. Multiple point-in-time copies are obtained for each database. A point-in-time copy retrieves data changed in the database since the retrieval of a previous point-in-time copy. A virtual database (VDB) is created by creating a set of files in the data storage system. Each file in the set of files created for a VDB is linked to the database blocks on the database storage system associated with a point-in-time copy of the source database. The set of files associated with the VDB are mounted on a database server allowing the database server to read from and write to the set of files. Workflows based on VDBs allow various usage scenarios based on databases to be implemented efficiently, for example, testing and development, backup and recovery, and data warehouse building.

Abstract: Online conversion procedures avoid the need to generate a copy of an entire table in order to convert the data type of a column in the table. To convert a table's column to a new data type, a replacement column is created in the table, the replacement column having the new data type. A background process dedicated to converting the column translates values in the column of the old data type to the new data type and stores the converted values in the replacement column. In addition, as transactions of users are applied to rows in the table, the value in the column of the old data type in the rows is converted and stored in the replacement column. Once the background process completes, the replacement column is used in lieu of the converted column.

Abstract: Systems, methods and computer program products for bookkeeping of download stamps are described herein. An embodiment includes augmenting database table (or mobile business object) metadata with a synchronization (“sync”) key and assigning a unique identifier to each sync key. A sync key is assigned to one or more rows (or records) in the database table and a download timestamp is associated with each sync key.
