Data Loading

If you have defined a graph schema, you can load data into the graph store. Loading data is a two-step process:

  1. Define a loading job, in which you use data loading statements to specify how values in the data source are extracted, transformed, and loaded their destinations.

  2. Run the loading job. If you have parameterized certain values when defining the loading job, you can supply the parameters when you run the loading job.

To learn about the GSQL statements used in defining a loading job, see GSQL language reference: Creating a loading job.

Data loaders

Data loaders are interfaces built in to the TigerGraph system that enable users to use the same high-level GSQL protocol for high-speed parallel data loading, whether the data reside directly on the network file system, or come from one of several other supported data sources.

The data loaders will stage temporary data files on the database server’s disk. You should have free disk space of at least 2 times the size of your total (uncompressed) input data.

When the data are coming from another data source, some initial configuration is needed. Then you can use the same type of loading jobs described in the GSQL language reference: Creating a loading job.

To configure a data source, see the appropriate data loader user guide:
