Abstract: A SQL database system is disclosed for reading and writing a non-SQL document store using SQL. The database system includes a SQL query engine configured to use different types of dynamically loadable connectors adapted to communicate with the non-SQL document store via its data access interface. The connectors may include a first connector that treats data within an individual document in the document store as multiple table rows, and a second connector that treats individual documents as individual table rows. In some embodiments, both types of document access modes may be implemented by a single multi-modal connector. In some embodiments, the connector may enable a table to be stored across multiple documents and provide the document identifier of the documents as an attribute of the table. Advantageously, by allowing multiple rows to be stored in individual documents, a table can be stored using less storage space and accessed more efficiently.

Abstract: A database system stores a table as a set of column files in a columnar format in a manner that improves the write performance of the table and avoids use of separate metadata repository. In embodiments, each column file groups values into entity chunks indexed by an entity index. Each chunk includes a live value index that determines which rows in chunk has live values. New values are written to the column file by appending an updated copy of the entity chunk. The entity index to refer to the newly written chunk as the latest version. This approach avoids expensive in-place updating of individual column values and allows the update to be performed much more quickly. In embodiments, the database system encodes metadata such as table schema information using file naming and placement conventions in the file store, so that a centralized metadata repository is not required.

Abstract: Embodiments of a transactional database system are described to implement transaction processing over database objects stored in a strongly consistent object storage system. When a transaction is initiated, the system makes a private copy of data objects that are used by the transaction. Reads and writes of the transaction will be performed on the private copy. When the transaction is to be committed, the system verifies that the committed state of the data objects has not changed outside the transaction, and updates metadata object(s) in the data storage system to point to the private copy as the currently committed state of the data objects. If the committed state of any data objects has changed during the transaction, the private copy is abandoned and the transaction is rolled back and/or retried.
