# To enable SurrealDB, uncomment the following section and update the engine line above
# See SURREALDB_SETUP_GUIDE.md for setup instructions

# [surrealdb]
# # Connection URL - choose one:
#
# # Option 1: Embedded in-memory (no server needed, fast for testing)
# url = "mem://"
#
# # Option 2: Embedded file-based (no server needed, persistent)
# # url = "file:///tmp/surrealdb.db"
#

# NOTES
# ============================================================================
#
# SQLite (default):
# - Single-file database: ~/.local/share/core/workspace.db
# - No server required
# - Good for: Local development, single-user scenarios
# - Limitations: Limited concurrency for high-traffic scenarios
#
# SurrealDB (optional):
# - Modern multi-backend database
# - Supports multiple deployment modes (embedded, server, cloud)
# - Good for: Production, scaling, advanced queries
# - Requires: Server mode setup or embedded library
#
# For production deployment guidance:
# See: SURREALDB_SETUP_GUIDE.md
#
# For database migration:
# See: SURREALDB_2_3_MIGRATION.md
