Queries a Neo4j graph database to retrieve nodes of type dbo_ConceptHouses with a configurable limit on the number of results returned.

Purpose

This function is designed to fetch concept house nodes from a Neo4j database, specifically targeting nodes labeled as 'dbo_ConceptHouses'. It's useful for retrieving architectural or conceptual housing data from a knowledge graph, with built-in result limiting to prevent overwhelming queries. The function relies on an external 'run_query' helper function to execute the Cypher query.

Source Code

def get_all_dbo_concepthouses(limit=100):
    """Return dbo_ConceptHouses nodes (limited to 25)"""
    query = """
    MATCH (n:dbo_ConceptHouses)
    RETURN n
    LIMIT $limit
    """
    return run_query(query, {"limit": limit})

Parameters

Parameter Details

limit: Integer value that controls the maximum number of dbo_ConceptHouses nodes to return from the database. Default is 100, though the docstring incorrectly states 25. Must be a positive integer. Higher values may impact performance depending on database size.

Return Value

Returns the result of the run_query function execution, which typically contains a list or collection of Neo4j node objects matching the dbo_ConceptHouses label. The exact return type depends on the implementation of run_query, but commonly returns a list of dictionaries or Neo4j Record objects containing node properties. Returns up to 'limit' number of nodes.

Dependencies

• neo4j

Required Imports

from neo4j import GraphDatabase

Usage Example

# Assuming run_query is defined and Neo4j connection is configured
# Example run_query implementation:
def run_query(query, params):
    driver = GraphDatabase.driver('bolt://localhost:7687', auth=('neo4j', 'password'))
    with driver.session() as session:
        result = session.run(query, params)
        return [record['n'] for record in result]
    driver.close()

# Get default 100 concept houses
results = get_all_dbo_concepthouses()
print(f'Retrieved {len(results)} concept houses')

# Get only 10 concept houses
limited_results = get_all_dbo_concepthouses(limit=10)
for house in limited_results:
    print(house)

Best Practices

• The docstring incorrectly states the limit is 25 when the default parameter is 100 - this should be corrected for consistency
• Ensure the run_query function properly handles database connections and closes them to prevent connection leaks
• Consider adding error handling for cases where the database is unavailable or the query fails
• Be mindful of the limit parameter when working with large datasets to avoid performance issues
• Consider adding type hints for better code documentation (e.g., limit: int -> List[Dict])
• The function assumes run_query is available in scope - ensure proper import or definition
• For production use, implement proper connection pooling and session management in run_query
