bulk-index-entities clj

(bulk-index-entities conn max-children min-children part-fn)

Bulk indexes all the entries in the database that have Hilbert values. Use this when first seeding the database.

bulk-tx clj

(bulk-tx ents tree-id max-children min-children cost-fn)

(bulk-tx ents tree-id max-children min-children cost-fn part-fn)

cost-partition clj

(cost-partition entities max-children min-children cost-fn)

Partition the entities up, minimising the cost-fn for each partition.

create-levels clj

(create-levels ents partition-fn max-children)

create-node clj

(create-node children)

dyn-cost-partition clj

(dyn-cost-partition ents max-children min-children cost-fn)

(dyn-cost-partition ents max-children min-children cost-fn n-splits)

min-cost-index clj

(min-cost-index entities min-children cost-fn)

Calculate an index into the list of entities that minimises the given cost-fn. Must be at least as large as min-children.

p-cost-partition clj

(p-cost-partition entities max-children min-children cost-fn n-splits)

Parallel cost-partition function, chunks the data into n-splits.

partition-accum clj

(partition-accum entities max-children min-children cost-fn)

Produces an accumulating lazy seq of vectors containing a list of partitions and a list of entities yet to be partitioned at that step.
