Pacer Indices

Most graph traversals will start from an index. Pacer makes indices easy to work with by auto-selecting the best available index. Most of the time you simply do not need to think about indices.

Creating auto indices

Indices can be created using create_key_index for either vertices or edges. By default, all indices are at the scope of the entire graph, though there may be the possibility of using other strategies in vendor-specific code. Indices will be built when created, so this call can take a significant amount of time on a large graph.

Usage:

• graph.create_key_index(:property_name) By default, vertex indices are created.
• graph.create_key_index(:property_name, :vertex, opts_hash) Explicitly creating vertex index with implementation-specific options passed through
• graph.create_key_index(:property_name, :edge) Create an edge index

Dropping auto indices

Usage:

• graph.drop_auto_index(:property_name, :vertex)
• graph.drop_auto_index(:property_name, :edge)
