Pinot Project Incubation Status

This page tracks the project status, incubator-wise. For more general project status, look on the project website.

The Pinot project graduated on 2021-07-21


Pinot is a distributed columnar storage engine that can ingest data in real-time and serve analytical queries at low latency. There are two modes of data ingestion - batch and/or realtime. Batch mode allows users to generate pinot segments externally using systems such as Hadoop. These segments can be uploaded into Pinot via simple curl calls. Pinot can ingest data in near real-time from streaming sources such as Kafka. Data ingested into Pinot is stored in a columnar format. Pinot provides a SQL like interface (PQL) that supports filters, aggregations, and group by operations.

Incubation work items

Project Setup

This is the first phase on incubation, needed to start the project at Apache.

Item assignment is shown by the Apache id. Completed tasks are shown by the completion date (YYYY-MM-dd).

Identify the project to be incubated

date item
2018-10-18 Make sure that the requested project name does not already exist and check to be sure that the name is not already trademarked for an existing software product.
NA If request from an existing Apache project to adopt an external package, then ask the Apache project for the SVN module and mail address names.
NA If request from outside Apache to enter an existing Apache project, then post a message to that project for them to decide on acceptance.
NA If request from anywhere to become a stand-alone PMC, then assess the fit with the ASF, and create the lists and modules under the incubator address/module names if accepted.


date item
2018-10-20 Ask infrastructure to create source repository modules and grant the committers karma.
2018-10-18 Ask infrastructure to set up and archive mailing lists.
2018-10-16 Ask infrastructure to set up issue tracker (JIRA, Bugzilla).
2019-03-08 Migrate the project to our infrastructure.

These action items have to be checked for during the whole incubation process.

These items are not to be signed as done during incubation, as they may change during incubation. They are to be looked into and described in the status reports and completed in the request for incubation signoff.

Collaborative Development

  • Have all of the active long-term volunteers been identified and acknowledged as committers on the project? - YES
  • Are there three or more independent committers? (The legal definition of independent is long and boring, but basically it means that there is no binding relationship between the individuals, such as a shared employer, that is capable of overriding their free will as individuals, directly or indirectly.) - YES
  • Are project decisions being made in public by the committers? - YES
  • Are the decision-making guidelines published and agreed to by all of the committers? - YES

Licensing awareness

  • Are all licensing, trademark, credit issues being taken care of and acknowleged by all committers? - YES

Project Specific

Things to check for before voting the project out.

Organizational acceptance of responsibility for the project

  • If graduating to an existing PMC, has the PMC voted to accept it?
  • If graduating to a new PMC, has the board voted to accept it?

Incubator sign-off

  • Has the Incubator decided that the project has accomplished all of the above tasks?
