Dynamic Graph Partitioner
Memgraph supports dynamic graph partitioning which dynamically improves performance on badly partitioned dataset over workers. To enable it, the user should use the following flag when firing up the master node:
--dynamic_graph_partitioner_enable
Parameters
| Name | Default Value | Description | Range |
|---|---|---|---|
| --dgp_improvement_threshold | 10 | How much better should specific node score | |
| be to consider a migration to another worker. This represents the minimal | |||
| difference between new score that the vertex will have when migrated and the | |||
| old one such that it's migrated. | Min: 1, Max: 100 | ||
| --dgp_max_batch_size | 2000 | Maximal amount of vertices which should be | |
| migrated in one dynamic graph partitioner step. | Min: 1, Max: MaxInt32 |
