See below a draft of the board report for Jan. 17. I borrowed heavily from
past reports and the release notes but I think the necessary points are
covered. If there's any activity I'm missing, please let me know!
Cheers,

## Description:
Apache Calcite is a highly customizable framework for parsing and
planning queries on data in a wide variety of formats. It allows
database-like access, and in particular a SQL interface and advanced
query optimization, for data not residing in a traditional database.
Avatica is a sub-project within Calcite, and provides a framework
for building local and remote JDBC and ODBC database drivers. Avatica
has an independent release schedule, and since April 2017, it has its
own independent repository.
## Issues:
- There are no issues requiring board attention at this time.
## Activity:
Development and mailing list activity is steady for both Calcite and
its Avatica sub-project.
Calcite 1.15.0, was released in December with 50 issues are fixed by 22
contributors. Some features of note are a "server" module with DDL
support; dynamic parameters in the LIMIT and OFFSET and clauses;
refactoring the JDBC adapter to make it easier to plug in a new SQL
dialect; and a data profiling algorithm, that efficiently analyzes
large data sets with many columns, estimating the number of distinct
values in columns and groups of columns.
Our community continued growing this quarter, as two new committers
(Christian Beikov and Vova Vysotskyi) were added to the project.
Finally, members of the Calcite PMC along with external collaborators
submitted a paper to the industrial track of SIGMOD 2018.
