What the board has decided about this committee or office, and the reports it filed, most recent first. Generated from the published minutes.
These categorised views are best effort. They are read from the published minutes by a program, and what it can attribute to a committee depends on how each resolution happens to be worded — so a page may be incomplete, and nothing here overrides the minutes themselves. The raw minutes are the source of truth.
Please note. The board approves the minutes of a meeting at the meeting after it, and they are published then - so the most recent meeting is not usually here. ASF Members can read the draft in the board's own repository until it is.

Lens aims to cut the Data Analytics silos by providing a single view of data across multiple tiered data stores and optimal execution environment for the analytical query. It seamlessly integrates Hadoop with traditional data warehouses to appear like one. ## Issues: There are no issues requiring board attention at this time. ## Membership Data: Apache Lens was founded 2015-08-19 (5 years ago) There are currently 23 committers and 18 PMC members in this project. The Committer-to-PMC ratio is roughly 6:5. Community changes, past quarter: - No new PMC members. Last addition was Puneet Gupta on 2016-09-20. - No new committers. Last addition was Rajitha R on 2018-02-09. ## Project Activity: There has been no activity on the project for the past quarter. Though we have discussed roadmap and suggestions in the earlier quarter, there is no work done in past quarter for the same. We will reinitiate the thread on roadmap, and see if we can do any changes or improvements to the project. If there is no clear roadmap, we will call for retiring the project next quarter. ## Community Health: There has been no change in community participation. Since there is no activity on project, community is mostly silent.

Lens aims to cut the Data Analytics silos by providing a single view of data across multiple tiered data stores and optimal execution environment for the analytical query. It seamlessly integrates Hadoop with traditional data warehouses to appear like one ## Issues: There are no issues requiring board attention at this time ## Activity: A bug fix and few improvements suggested by one of the contributors. ## Health report: As we saw on the roll-call, PMC is active and responsive. The project is being used in at least one of the organizations that we know of, where it is being used in sustenance mode with occasional changes being made. We are looking at two of the contributors who are making occasional contributions as prospective new committers. Project has not been actively looking for new committers or PMC, as existing committers and PMC are responsive. But PMC has not done an outreach to users to get them more engaged. ## PMC changes: - Currently 18 PMC members. - No new PMC members added in the last 3 months - Last PMC addition was Puneet Gupta on Tue Sep 20 2016 ## Committer base changes: - Currently 23 committers. - No new committers added in the last 3 months - Last committer addition was Rajitha R at Fri Feb 09 2018 ## Releases: - Last release was 2.7 on Tue Feb 06 2018

over datasets stored in multiple warehouses. Lens integrates Apache Hive
with other data warehouses by tiering them together to form logical data
cubes.
Lens has been incubating since 2014-10-10.
Three most important issues to address in the move towards graduation:
We had discussion about "where is Lens with respect to graduation" on dev
mailing list. Most of PPMC and mentors feel that Lens is ready to
graduate. http://s.apache.org/rYP
We intend to start preparing the graduation vote, following the
discussion.
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be

Lens is a platform that enables multi-dimensional queries in a unified way
over datasets stored in multiple warehouses. Lens integrates Apache Hive
with other data warehouses by tiering them together to form logical data
cubes.
Lens has been incubating since 2014-10-10.
Three most important issues to address in the move towards graduation:
1. Grow user and developer community and add more committers
2. Document all features and do one more release

Shepherd/Mentor notes:
Alan Cabrera (adc):
Very good report; an exemplar of how reports should be done. The
community seems very active and healthy. IMO, only items 1 & 2 are
required for graduation.
