To show new events appearing, one can run :sql:`SELECT * FROM meetupRsvp ORDER
BY mtime DESC LIMIT 50` repeatedly, which shows the
last events that were ingested by Pinot.
+Experimenting with Pinot
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Now we have a quick start Pinot cluster running locally. The below shows a
step-by-step instruction on
+how to add a simple table to the Pinot system, how to upload segments, and how
to query it.
+
+Suppose we have a transcript in CSV format containing students' basic info and
their scores of each subject.
+
++------------+------------+-----------+-----------+-----------+-----------+
+| studentID | firstName | lastName | gender | subject | score |
++============+============+===========+===========+===========+===========+
+| 200 | Lucy | Smith | Female | Maths | 3.8 |
++------------+------------+-----------+-----------+-----------+-----------+
+| 200 | Lucy | Smith | Female | English | 3.5 |
++------------+------------+-----------+-----------+-----------+-----------+
+| 201 | Bob | King | Male | Maths | 3.2 |
++------------+------------+-----------+-----------+-----------+-----------+
+| 202 | Nick | Young | Male | Physics | 3.6 |
++------------+------------+-----------+-----------+-----------+-----------+
+
+Firstly in order to set up a table, we need to specify the schema of this
transcript.
+
+.. code-block:: none
+
+ {
+ "schemaName": "transcript",
+ "dimensionFieldSpecs": [
+ {
+ "name": "studentID",
+ "dataType": "STRING"
+ },
+ {
+ "name": "firstName",
+ "dataType": "STRING"
+ },
+ {
+ "name": "lastName",
+ "dataType": "STRING"
+ },
+ {
+ "name": "gender",
+ "dataType": "STRING"
+ },
+ {
+ "name": "subject",
+ "dataType": "STRING"
+ }
+ ],
+ "metricFieldSpecs": [
+ {
+ "name": "score",
+ "dataType": "FLOAT"
+ }
+ ]
+ }
+
+To upload the schema, we can use the command below:
+
+.. code-block:: none
+
+ $
./pinot-distribution/target/apache-pinot-incubating-0.1.0-SNAPSHOT-bin/apache-pinot-incubating-0.1.0-SNAPSHOT-bin/bin/pinot-admin.sh
AddSchema -schemaFile /Users/jlli/transcript-schema.json -exec
+ Executing command: AddSchema -controllerHost 172.25.119.20 -controllerPort
9000 -schemaFilePath /Users/jlli/transcript-schema.json -exec
