Notes below: - * - * This interface began as the SortedDataInterface, a way to hide the fact that there were two - * on-disk formats for the btree.

Many other storage engines provide different Btree(-ish) implementations. This interface - * could allow those interfaces to avoid storing btree buckets in an already sorted structure. - * - * TODO: See if there is actually a performance gain. - * - * 2. The existing btree implementation is written to assume that if it modifies a record it is - * modifying the underlying record. This interface is an attempt to work around that. - * - * TODO: See if this actually works. + * This is the uniform interface for storing indexes and supporting point queries as well as range + * queries. The actual implementation is up to the storage engine. All the storage engines must + * support an index key size up to the maximum document size. */ class SortedDataInterface { public: |
