Abstract
The disclosed technology generally describes separating types of data chunks in a copy-on-write/MVCC B+ tree, chunk-based data storage system, and also allocating the sizes of leaf chunks to be smaller than that of other (e.g., internal and root node) chunks. By having leaf chunks separate from node chunks, the probability of having a fully reclaimable (without copying) chunk is increased. Similarly, by having smaller sized leaf chunks relative to node chunks, the probability of having a fully reclaimable (without copying) leaf chunks is increased. The technology thus facilitates more efficient garbage collection.
