HAMMER Filesystem Progress
"I will be continuing to commit bits and pieces of HAMMER, but note that it will probably not even begin to work for quite some time," Matthew Dillon reported on the new clustering filesystem he's developing for DragonFlyBSD. He noted, "I am still on track for it to make it into the end-of-year release." Matt continued:
"My B-Tree implementation also allows HAMMER to cache B-Tree nodes and start lookups from any internal node rather then having to start at the root. You can do this in a standard B-Tree too but it isn't necessarily efficient for certain boundary cases. In my implementation I store boundaries for the left AND right side which means a search starting in the middle of the tree knows exactly where to go and will never have to retrace its steps."
