This section describes the Java APIs that are used to execute PGQL queries in the In-Memory graph server (PGX).

• Getting Started with PGQL
  
• PGQL Features Supported in the Graph Server (PGX)
  
• Java APIs for Executing CREATE PROPERTY GRAPH Statements
  
• Python APIs for Executing CREATE PROPERTY GRAPH Statements
  
• Java APIs for Executing SELECT Queries
  This section describes the APIs to execute SELECT queries in the In-Memory graph server (PGX).
• Java APIs for Executing UPDATE Queries
  The UPDATE queries make changes to existing graphs using the INSERT, UPDATE, and DELETE operations as detailed in the section Graph Modification of the PGQL 1.3 specification.
• PGQL Queries with Partitioned IDs
  
• Security Tools for Executing PGQL Queries
  To safeguard against query injection, bind variables can be used in place of literals while printIdentifier(String identifier) can be used in place of identifiers like graph names, labels, and property names.
• Best Practices for Tuning PGQL Queries
  This section describes best practices regarding memory allocation, parallelism, and query planning.
