SHOW STATS

The SHOW STATS statement shows the statistics of the graph space collected by the latest STATS job.

The statistics include the following information:

  • The number of vertices in the graph space
  • The number of edges in the graph space
  • The number of vertices of each tag
  • The number of edges of each edge type

Prerequisites

You have to run the SUBMIT JOB STATS statement in the graph space where you want to collect statistics. For more information, see SUBMIT JOB STATS.

Caution

The result of the SHOW STATS statement is based on the last executed SUBMIT JOB STATS statement. If you want to update the result, run SUBMIT JOB STATS again. Otherwise the statistics will be wrong.
