Alexander Shopov commented on CASSANDRA-10031:
----------------------------------------------
Just some initial stats:
> At a minimum in the start of each run() method
I believe you mean all implementations of Runnable.run and Thread.start methods:
Whole project:
Runnable.run: 198 occurrences
Thread.start: 36 occurances
src/java:
Runnable.run: 25 occurrences
Thread.start: 19 occurances
The second numbers seem more representative and in need to be instrumented.
> Name threads for improved ops/debugging
> ---------------------------------------
>
> Key: CASSANDRA-10031
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10031
> Project: Cassandra
> Issue Type: Improvement
> Reporter: T Jake Luciani
> Priority: Minor
> Labels: lhf
> Fix For: 3.x
>
>
> We currently provide basic names for threads in threads like {{STREAM-IN-1}}
> which gives some basic information about what the job of the thread is.
> When looking at a log statement or jstack it's helpful to have this context.
> For our work stealing thread pool we share threads across all thread pools so
> we lose this insight.
> I'd like to propose we start using the Thread.currentThread().setName("")
> In different aspects of the code to improve insight as to what cassandra is
> doing at any given moment.
> * At a minimum in the start of each run() method.
> Ideally for much finer grain things.
> * In compaction include the partition name currently being working on.
> * In SP include the client ip
> Etc...
