Reload a table segment

Reload a table segment in Apache Pinot.

When Pinot writes data to segments in a table, it saves those segments to a deep store location specified in your table configuration, such as a storage drive or Amazon S3 bucket.

If a new column is added to your table or schema configuration during ingestion, incorrect data may appear in the consuming segment(s). To ensure accurate values are reloaded, see how to add a new column during ingestion.

Use the Pinot Controller API to reload segments

To reload all segments from a table, use:

POST /segments/{tableName}/reload

To reload a specific segment from a table, use:

POST /segments/{tableName}/{segmentName}/reload

A successful API call returns the following response:

{
    "status": "200"
}

Use the Pinot Admin Console to reload segments

To use the Pinot Admin Console, do the following:

1. From the left navigation menu, select Cluster Manager.

2. Under TENANTS, select the Tenant Name.

3. From the list of tables in the tenant, select the Table Name.

4. Do one of the following:

   • To reload all segments, under OPERATIONS, click Reload All Segments.

   • To reload a specific segment, under SEGMENTS, select the Segment Name, and then in the new OPERATIONS section, select Reload Segment.
