First Batch Ingest

Import your first batch of data into Pinot and see it appear in the query console.

Outcome

By the end of this page you will have imported CSV data into your transcript offline table and confirmed the rows are queryable.

Prerequisites

• Completed First table and schema -- the transcript_OFFLINE table must already exist.

• The sample CSV file at /tmp/pinot-quick-start/rawdata/transcript.csv from the previous step.

• For Docker users: set the PINOT_VERSION environment variable. See the Version reference page.

Steps

1. Understand batch ingestion

Batch ingestion reads data from files (CSV, JSON, Avro, Parquet, and others), converts them into Pinot segments, and pushes those segments to the cluster. A job specification YAML file tells Pinot where to find the input data, what format it is in, and where to send the finished segments.

2. Create the ingestion job spec

Local

Create the file /tmp/pinot-quick-start/batch-job-spec.yml:

/tmp/pinot-quick-start/batch-job-spec.yml

executionFrameworkSpec:
  name: 'standalone'
  segmentGenerationJobRunnerClassName: 'org.apache.pinot.plugin.ingestion.batch.standalone.SegmentGenerationJobRunner'
  segmentTarPushJobRunnerClassName: 'org.apache.pinot.plugin.ingestion.batch.standalone.SegmentTarPushJobRunner'
  segmentUriPushJobRunnerClassName: 'org.apache.pinot.plugin.ingestion.batch.standalone.SegmentUriPushJobRunner'
jobType: SegmentCreationAndTarPush
inputDirURI: '/tmp/pinot-quick-start/rawdata/'
includeFileNamePattern: 'glob:**/*.csv'
outputDirURI: '/tmp/pinot-quick-start/segments/'
overwriteOutput: true
pinotFSSpecs:
  - scheme: file
    className: org.apache.pinot.spi.filesystem.LocalPinotFS
recordReaderSpec:
  dataFormat: 'csv'
  className: 'org.apache.pinot.plugin.inputformat.csv.CSVRecordReader'
  configClassName: 'org.apache.pinot.plugin.inputformat.csv.CSVRecordReaderConfig'
tableSpec:
  tableName: 'transcript'
  schemaURI: 'http://localhost:9000/tables/transcript/schema'
  tableConfigURI: 'http://localhost:9000/tables/transcript'
pinotClusterSpecs:
  - controllerURI: 'http://localhost:9000'

Docker

3. Run the ingestion job

Local

bin/pinot-admin.sh LaunchDataIngestionJob \
    -jobSpecFile /tmp/pinot-quick-start/batch-job-spec.yml

Docker

The job reads the CSV file, builds a segment, and pushes it to the controller. You should see log output ending with a success message.

Verify

1. Open the Query Console in your browser.

2. Run the following query:

SELECT * FROM transcript

1. You should see 4 rows returned, matching the CSV data you loaded:

studentID	firstName	lastName	gender	subject	score	timestampInEpoch
200	Lucy	Smith	Female	Maths	3.8	1570863600000
200	Lucy	Smith	Female	English	3.5	1571036400000
201	Bob	King	Male	Maths	3.2	1571900400000
202	Nick	Young	Male	Physics	3.6	1572418800000
