REBUILD {TAG | EDGE} INDEX [<index_name_list>]

    [index_name [, index_name] ...]

Use REBUILD INDEX to rebuild the created tag or edge type index. For details on how to create an index, see CREATE INDEX.

Multiple indexes are permitted in a single REBUILD statement, separated by commas. When the index name is not specified, all tag or edge indexes are rebuilt.

If the index is created before data insertion, there is no need to rebuild the index. If data is updated or newly inserted before the index creation, you need to rebuild the indexes to make sure that the indexes contain the previously added data.

NOTE: During the rebuilding, all queries skip the index and perform sequential scans. This means that the return results can be different because not all the data is indexed during rebuilding.

After rebuilding is complete, you can use the SHOW {TAG | EDGE} INDEX STATUS command to check if the index is successfully rebuilt. For details on index status, see SHOW INDEX STATUS.

Nebula Graph creates a job to rebuild the index. The job ID is displayed in the preceding return message. To check if the rebuilding process is complete, use the SHOW JOB <job_id> statement. For more information, see SHOW JOB.
