143c3b3b4f Use large reads and large write 2016-07-16 16:09:47 +02:00

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

eb792daefc More preparations for not loading blocks in write() calls 2016-07-15 21:06:41 +02:00

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

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
