摘要： For electronic fare collection, an APP is downloaded onto a smartphone for automatic payment for transit fare. Upon successful registration of funds onto the APP an associated server system issues a fund indicator to the APP. Upon machine-reading the fund indicator by the validation terminal at the entry and exit gates in the transit station, the application server system calculates the transit fare and reissues the fund indicator with balance funds available after deducting the transit fare to the computer application module (APP). Indication of sufficient funds when scanned at the entry gate allows entry of the passenger through the entry gate. During the passenger's travel, the correctness of the funds is checked and a top up of insufficient funds requested before exiting through the exit gate.

摘要： Disclosed herein are system, method, and computer program product embodiments for accessing a distributed shared log that supports a total order over log writes and multiple logical log streams. An embodiment operates by selecting a range of log entries for a logical log stream from the distributed shared log and mapping the selected range of log entries to associated storage units in a plurality of storage units. The selected range of log entries are stored at the associated storage units according to metadata that indexes the selected range of log entries by logical log stream. The selected range of log entries are then requested from the associated storage units based on the mapping. The selected range of log entries for the logical log stream are then returned from the associated storage units based on a scan of the metadata. The received log entries are then reassembled.

摘要： A locking mechanism in a delta-store-based database to support long running transactions across multiple RID spaces is described. An example method includes establishing a column-based in-memory database including a main store and a delta store. A delete or an update statement is executed with a transaction on a table having plurality of table versions. The table versions are represented by bitmaps in the delta store and the bitmaps and table fragments corresponding to the table versions implement RID spaces for the table. A lock on a row of the table manipulated by the delete or the update statement is requested to preclude other transaction from deleting or updating an obsolete version of data. Upon a successful validation that the row to be locked is not the obsolete version in the RID spaces of the table, a lock is granted to the transaction.

摘要： Embodiments described herein generally relate to providing durability of in memory columnar datastores using multiple logs. A computer-implemented method is described. The method includes receiving a request to perform a transaction involving multiple tables in a column-oriented database system. The method further includes performing the transaction on each of the two or more database tables. Performance of the transaction generates two or more commit fragments corresponding to each of the two or more database tables. The method further includes writing each commit fragment to a transaction log for each of the two or more database tables. The method also includes writing a commit record for the transaction to a commit log after all commit fragments have been written.
