Ragex.Store.Backend.Dllb (Ragex v0.19.0)

dllb-backed storage implementation for Ragex's knowledge graph.

Delegates all operations to Dllb.MetaAST.Query and the dllb connection pool. Provides native HNSW vector search, graph traversal, and full-text search capabilities that are orders of magnitude faster than the ETS brute-force equivalents on large datasets.

Requirements

The dllb server must be running and configured:

config :dllb,
  enabled: true,
  host: "127.0.0.1",
  port: 3009,
  pool_size: 5

Summary

Functions

schema_statements()

Returns the ordered list of schema statements executed by bootstrap/0.

Functions

schema_statements()

@spec schema_statements() :: [String.t()]

Returns the ordered list of schema statements executed by bootstrap/0.

The table, secondary-index, and edge-index definitions come from Dllb.Schema. The full-text and vector search indexes are built here so the vector index dimension can be resolved dynamically from the configured embedding model (see the :embedding_model config and Ragex.Embeddings.Registry). A static dimension that does not match the model's output makes the engine silently skip indexing every row.
