Black Forest Database: The Engine Beneath Everything
Black Forest Database™ (BFDB) is Craxel's multi modal, distributed OLTP engine. It is built for real time indexing and deterministic O(1) retrieval, so performance stays constant however large the data set grows.
Think of Black Forest as an onion. BFDB is the innermost layer, the database itself. Black Forest Knowledge Infrastructure is the platform built around it.
One engine natively supports SQL, graph, time series, spatial and key value data, structured and unstructured, which removes the need for several specialised databases and the duplication between them.

Conventional estates run a separate system for each data type, then pay to duplicate, replicate and reconcile between them.
BFDB treats all data spatially, which allows a single multi dimensional index to serve every modality. One copy of the data answers relational, graph, temporal, spatial and key value access patterns.
Complex joins, traversals and analytics run inside the engine, and because BFDB is OLTP the graph itself can be transactional. This suits mission critical workloads that need massive transactional scale, rapid ingestion and real time analytical queries directly against operational data.
The O(1) Hashing Algorithm
At the core is a patented hierarchy preserving probabilistic hash, which solves a difficult hash collision problem while retaining order. It is the single innovation behind both deterministic O(1) retrieval and high performance searchable encryption.
Because hierarchy is preserved, BFDB keeps the selectivity that conventional hashes discard. Range, bounding, interval and nearest neighbour queries are supported through SQL, SPARQL and a native API.
Indexing happens on arrival and in parallel rather than through a single entry point, with demonstrated rates of 1 gigabit per second using a pair of commodity cloud servers.
Persistence sits on low cost object storage, so petabyte volumes stay hot without partitioning across a large server cluster. BFDB runs as standalone database services at the edge, locally or in the cloud.
Fine grained access control is enforced inside the engine itself, and High Performance Searchable Encryption allows search and analytics over fully encrypted data without the data layer ever holding the keys.
