Summary

Monitoring Neo4j performance is crucial for efficient data management. To efficiently monitor Neo4j and identify problematic queries, it's essential to understand the query optimization techniques and best practices. These include using EXPLAIN and PROFILE commands to analyze execution plans, leveraging domain knowledge of the data and network topology, and applying efficient traversal methods such as Quantified Path Patterns (QPP) or custom plugins. Subqueries can be used to break complex queries into smaller units, reducing memory allocation and improving efficiency. List comprehensions should be avoided due to potential performance issues. Aggregation operations should be minimized to avoid excessive memory usage. Combining multiple queries in a single query can reduce memory consumption and improve response time. Using Cypher queries instead of APOC plugins when possible can also optimize performance. Load testing with tools like JMeter can help identify and refine problematic queries, leading to improved availability and performance. By applying these techniques and best practices, it's possible to achieve 99.99 percent availability in production while demonstrating the resilience of Neo4j.
