I'm very happy to work on this task and to try to help with the Iceberg effort, but it would be useful for me to have a bit more context as to what we believe needs to be done.

The description above doesn't give me much to work with at the moment. I've added @JAllemandou and @Ottomata who can hopefully point me in the right direction.

I see from T311525: Upgrade to latest PrestoDB and enable iceberg support that we already have updated presto debs (0.273.3) and that they are already available on the production presto servers.

btullis@an-presto1001:~$ apt-cache policy presto-server 
presto-server:
  Installed: 0.273.3-1
  Candidate: 0.273.3-1
  Version table:
 *** 0.273.3-1 1001
       1001 http://apt.wikimedia.org/wikimedia buster-wikimedia/main amd64 Packages
        100 /var/lib/dpkg/status

We can see that the analytics_iceberg catalog has been defined on the production cluster:

btullis@an-presto1001:~$ ls -l /etc/presto/catalog/
total 8
-r--r--r-- 1 presto presto 966 Nov 30 16:43 analytics_hive.properties
-r--r--r-- 1 presto presto 844 Jul  6  2022 analytics_iceberg.properties

...so I can do the following from a stats box.

btullis@stat1004:~$ presto --catalog analytics_iceberg
Picked up JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF-8
presto>

Does that mean that the presto part of this ticket is complete?

Should I be looking into adding iceberg support for Spark3 via conda-analytics?
