回复： [Proposal] Put some dependencies in our maintenance repo

[41108453]

Can you send an email to the cloudera maintenance team to explain this 
situation, and hope they will submit this to the central warehouse of maven

Hi Duo,

I found another dependency package with similar functions, let's see if I
can replace it.

Regarding the question of Calcite, we have previously investigated Calcite
for Doris to optimize the query framework.
After the evaluation, it is found that the access cost may be similar to
the reconstruction of the entire query framework , so it is a long-term
work in the future.

&gt; Could be a long term solution? Is there any other reason which prevents us
&gt; using Calcite?

&gt; &gt; Hi Duo,
&gt; &gt;
&gt; &gt; Using calcite directly will definitely not work, which means that the
&gt; query
&gt; &gt; analysis + planning are rewritten.
&gt; &gt; But&nbsp; maybe we can use other parser tools to replace it, or 
something
&gt; &gt; similar.
&gt; &gt; However, it is estimated that the amount of change for this solution.

&gt; &gt; &gt; I think this is used to generate the SQL parser? Is it possible 
to use
&gt; &gt; &gt; Calcite directly?

&gt; &gt; &gt; &gt; Hi,
&gt; &gt; &gt; &gt;
&gt; &gt; &gt; &gt; Currently, some fe dependencies that we rely on are not in 
the maven
&gt; &gt; &gt; repo.
&gt; &gt; &gt; &gt; For example, cup-maven-plugin and java-cup are located at 
the
&gt; Cloudera
&gt; &gt; &gt; &gt; 3rd-P.
&gt; &gt; &gt; &gt; This will lead to the risk that our code will not be 
compiled when
&gt; the
&gt; &gt; &gt; &gt; third-party repo changes.
&gt; &gt; &gt; &gt;
&gt; &gt; &gt; &gt; I have also tried whether it is possible to replace these
&gt; dependencies
&gt; &gt; &gt; &gt; with other packages or versions, but unfortunately the only 
thing we
&gt; &gt; can
&gt; &gt; &gt; &gt; use at the moment is this.
&gt; &gt; &gt; &gt;
&gt; &gt; &gt; &gt; So I propose whether we can maintain these jar packages in 
our own
&gt; repo
&gt; &gt; &gt; to
&gt; &gt; &gt; &gt; ensure that they can be found every time we compile?
&gt; &gt; &gt; &gt;
&gt; &gt; &gt; &gt; Or do you have any better solutions?
&gt; &gt; &gt; &gt;
