Usage: spacetime start [OPTIONS]

Options:
  -l, --listen-addr <LISTEN_ADDR>
          The address and port to listen for HTTP requests on
          
          [default: 0.0.0.0:3000]

      --data-dir <DATA_DIR>
          Directory for spacetimedb files

      --enable-tracy
          Enable the Tracy profiler

      --jwt-pub-key-path <JWT_PUB_KEY_PATH>
          Path to a public key (ECDSA/PKCS-8/PEM) for JWT validation

      --jwt-priv-key-path <JWT_PRIV_KEY_PATH>
          Path to a private key (ECDSA/PKCS-8/PEM) for signing JWTs

      --in-memory
          Don't use file-based persistence for the database

      --page_pool_max_size <PAGE_POOL_MAX_SIZE>
          Maximum size of page pool. This is a soft limit: only relevant
          while page pool is not full. If page pool is full, it will
          allocate additional memory. Must be a multiple of 64KiB.
          
          [default: 8GiB]

      --pg-port <PG_PORT>
          Port to bind for Postgres compatibility endpoint

      --non-interactive
          Don't run in interactive mode

  -h, --help
          Print help
