How to fix "Error: This QuadStore is not registered"?

Question

I am trying to load a sample chinook.db database into Cayley. I am using a standart Cayley config file cayley_example.yml with small changes specific to sqlite3.

Here's chinook.db

cayley_example.yml

store:
  # backend to use
  backend: sqlite
  # address or path for the database
  address: "./chinook.db"
  # open database in read-only mode
  read_only: false
  # backend-specific options
  options:
    nosync: false
query:
  timeout: 30s
load:
  ignore_duplicates: false
  ignore_missing: false
  batch: 10000

If I execute ./cayley init -c cayley_example.yml, I get Error: This QuadStore is not registered. I tried to follow this guide but .cfg files are not supported by the current Cayley version.

Answer 1

Check if Cayley version that you use supports SQLite:

cayley -h

You would see a list of supported backends in the help message for -d option:

  -d, --db string  database backend to use:
                   badger, bolt, btree, ..., mysql, postgres, sql (default "memstore")

If you built the binary from source, make sure you built the latest one and CGO_ENABLED=1 is set.

Answer 2

While running the command cayley init, add flag -d and "storage type". For your case- cayley init -d "sql"
