-----------------------------------------
Summary: Make DF and BF collector implementations coexists
Key: MRESOLVER-248
URL: https://issues.apache.org/jira/browse/MRESOLVER-248
Project: Maven Resolver
Issue Type: Improvement
Components: Resolver
Reporter: Tamás Cservenák
There is ongoing work to fundamentally change {{DependencyCollector}}
implementation in resolver.
Resolver was from beginning building dependency graph by doing "depth first"
(df) approach, and was downloading POMs sequentially during collection.
With work happing under MRESOLVER-240, MRESOLVER-247 and MRESOLVER-7, collector
is altered: is doing now "breadth first" (bf), implements skip-reconcile and
will have parallel POM download implemented.
Still, IMHO letting both (original "df" and new "bf") coexists is technically
simple, and would allow us not only simpler comparison of the performance of
the two, but there is a possibility that there will be no "one size fit all"
solution, so having both knives in drawer is just a win-win. Ultimately, we MAY
prove superiority of one over another, essentially leaving only one collector
implementation, as in that case this issue (and the "coexistence indirection"
should be just removed) and not enlist it in release notes of upcoming 1.8.0
version.
