I'm also okay with leaving [db_name]. I think a separate top-level page or even 
just a paragraph showing the proper syntax would be even better.

If you want to make it even clearer that all files are rewritten (not just the 
ones with the latest schema), you could write "rewrite all files, converting 
them (if necessary) to the latest table schema".
I'm not sure it's needed, I'm also okay with the current wording.

[] is quite standard notation, and we are using it extensively in the Impala 
docs, e.g.: 
https://impala.apache.org/docs/build/html/topics/impala_create_table.html

So users shouldn't be confused by it. This file mostly contains simple examples 
because the other statements have their own detailed doc page. But we don't 
have that for OPTIMIZE, so having a proper syntax definition here makes sense 
to me. Alternatively, you we could create a separate top-level page for 
OPTIMIZE, and here only add a few examples.

PS2, Line 561: rewrites the entire table
I think we should mention that it only applies to the current implementation, 
so users won't have this assumption in future releases.

PS2, Line 587: rewrites the entire table
Maybe also mention here that this behavior is temporary.

Thanks NoƩmi!

File docs/topics/impala_iceberg.xml:

http://gerrit.cloudera.org:8080/#/c/21320/1/docs/topics/impala_iceberg.xml@553
PS1, Line 553: many small,
 : delete
It doesn't feel right for me, maybe "can write many small data files and/(as 
well as) delete files.


http://gerrit.cloudera.org:8080/#/c/21320/1/docs/topics/impala_iceberg.xml@554
PS1, Line 554: update
Do we have 'update files'? My understanding is that an update adds new data 
files and delete files. If this is correct, I don't think we should call them 
'update files'. Of course we should mention that updates (as well as deletes 
and inserts) contribute to the problem.


http://gerrit.cloudera.org:8080/#/c/21320/1/docs/topics/impala_iceberg.xml@556
PS1, Line 556: db_name
Do we always have to use the fully qualified name? If not, it may not be 
important to include the database name here.


http://gerrit.cloudera.org:8080/#/c/21320/1/docs/topics/impala_iceberg.xml@577
PS1, Line 577:   Views cannot be optimized.
Maybe take it out of the list into a separate paragraph because it doesn't fit 
well with the introduction of the list ("To execute table optimization:").


http://gerrit.cloudera.org:8080/#/c/21320/1/docs/topics/impala_iceberg.xml@585
PS1, Line 585: 
Do you think it would be worth to add a warning that because OPTIMIZE re-writes 
the whole table, it can take a long time, so it shouldn't be called too often?

There are no such files as 'udpdate files', so I'd just use 'data files'

PS1, Line 565:   rewrite files using the latest table schema
 :   rewrite partitions according to the latest 
partition spec
I would slightly phrase it differently, as the current phrasing might suggest 
that data files with old schema/partition spec are getting selected for rewrite.

So maybe:
"the newly written files will have the latest schema and partitioned based on 
the latest partition spec"
