alamb opened a new issue #146:
URL: https://github.com/apache/arrow-datafusion/issues/146


   *Note*: migrated from original JIRA: 
https://issues.apache.org/jira/browse/ARROW-11214
   
   As we expand the numbers of functions available in DataFusion, DataFusion 
will likely pick up additional third-party dependencies. In general, I think it 
would be a nice feature for DataFusion to  allow users more fine grained 
control over the features that they wanted to use (and pay the subsequently 
higher compilation / link time (and binary size) cost. At the moment, with a 
single codebase and no feature flags, everyone's compile time and binary size 
will increase even if they don't use a specific set of features. 
   
   It seems to me like we might want to start offering a way to keep the number 
of required dependencies of DataFusion down. For example, in the case of 
https://github.com/apache/arrow/pull/9139, we could potentially put the use of 
crypto functions behind a feature flag. Users of DataFusion could then pick a 
subset of features  like "core" and "func-datetime" and "func-crypto" to have 
more control over the dependencies they pulled in
