Tomo Suzuki updated CASSANDRA-15453:
------------------------------------
    Description: 
Can we backport the Guava version upgrade (CASSANDRA-15248) into 3.11 branch?

h3. Background

I'm trying to upgrade Apache Beam's dependencies to latest versions. Apache 
Beam depends on Cassandra 3 ({{org.apache.cassandra:cassandra-all:3.11.3}}).
Cassandra 3's dependency on Guava's old fields (potentially and methods), such 
as CharMatcher.DIGIT, are blocking Apache Beam's Guava dependency upgrade 
(BEAM-8911). The field is removed in Guava 26.0. Because of this, Apache Beam's 
Guava dependency must be lower than version 26.0.

I see the latest cassandra-all release on 3.X is 3.11.5, which still relies on 
Guava 18. This version does not have {{CharMatcher.digit()}}, the replacement 
of old {{CharMatcher.DIGIT}}. To get rid of {{CharMatcher.DIGIT}} and thus let 
Apache Beam to use Guava 26 and higher, we need to upgrade Cassandra's Guava 
version.

h3. How about waiting for Cassandra version 4(-alpha)?

I thought about Cassandra "4", which has a recent version of Guava. However, I 
believe quite a few Cassandra/Beam users will keep using Casandra 3 for several 
years. I want such users to be able to use the higher version of Guava. 
h3. CASSANDRA-15248 "Upgrade Guava to latest on master branch",

h3. Shading?

Shading makes build process complex. When things go wrong due to this, it's 
hard to debug ([JLBP18|https://jlbp.dev/JLBP-18.html]). 


I found CASSANDRA-15248 "Upgrade Guava to latest on master branch", but this 
did not go into 3.11 branch. Can we backport this Guava version upgrade 
(CASSANDRA-15248) into 3.11 branch?

h3. Background

Cassandra 3's dependency on old fields (potentially and methods), such as

(BEAM-8911). Beam's Guava dependency is limited at most lower than version 26.0.

Guava 18. This version does not have {{CharMatcher.digit()}}, the replacement
