Cypher runtimes

The runtime is the final step of a Cypher^® query, where query plans received from the planner are executed as quickly and efficiently as possible.

Cypher has three available runtimes: slotted, pipelined, and parallel. Though the default runtime generally provides the best performance, there are situations when deciding which runtime to use is an important part of maximizing the efficiency of queries. It is, therefore, important for advanced users to understand the different runtimes offered by Neo4j.

This chapter contains the following sections:

Runtime concepts - a deep-dive into the concepts behind Cypher runtimes.
Parallel runtime: reference - information about queries, configuration settings, and using the parallel runtime on Aura.
