AQL Execution and Performance
This chapter describes AQL features related to query execution and query performance
All queries that have successfully run to completion return statistics about the execution
Clients can check if given AQL queries are syntactically valid using an HTTP API or JavaScript API
You can explain and profile AQL queries to inspect the execution plans and to understand the performance characteristics, as well as create debug packages for reporting issues
For understanding the performance of specific queries, you can profile them to identify slow parts of query execution plans
AQL queries are sent through an optimizer before execution that creates an initial execution plan, looks for optimization opportunities, and applies them
AQL provides an optional query results cache in single server deployments
