e38c0f1e8b Fix isRightBorderNode when growing trees 2016-07-17 10:32:59 +02:00
Sebastian Messmer
bbdd8a548b Special case treatment for traversals until exactly the last leaf has to load the last leaf to grow it. Before this commit, we just always loaded the last traversed leaf and checked its size. Now we only do so if it's the right border leaf. This saves us loading some leaves. 2016-07-17 10:16:09 +02:00
Sebastian Messmer
eab7cb1df4 Implement BlockStore::overwrite(). This is the last step in ensuring that the write() call doen't have to load leaves if they're only overwritten anyhow. 2016-07-16 11:42:06 +02:00
Sebastian Messmer
eb792daefc More preparations for not loading blocks in write() calls 2016-07-15 21:06:41 +02:00
Sebastian Messmer
d80b95514e Traversal doesn't load leaves, but returns the key. This way, the write() call can (after a future commit) write to full leaves without loading them beforehand. 2016-07-15 20:12:24 +02:00

3f04a7411c If tree depth increases, and we already traversed the old tree, don't go into it again to grow its last leaf. 2016-07-14 14:23:15 +02:00

0dbfdf3e2b When shrinking a tree, LeafTraverser takes care of decreasing tree depth, not DataTree anymore. This way, LeafTraverser is now responsible for increasing and decreasing depth as necessary. 2016-07-14 12:55:54 +02:00

35a4e42ba5 Small fixes in traversal algorithm 2016-07-14 12:38:25 +02:00

9e9369b9ed Performance optimization: When removing or shrinking a tree, we don't load/read leaves anymore. Loading inner nodes is enough to get all block IDs and then we can delete the leaves from their IDs without loading them. 2016-07-13 11:27:31 +02:00
