I have a table is SALT_BUCKETS = 12, but it has 14 regions, is this right?
Thanks
It’ll start with 12 regions, but those regions may split as they’re written
to.

Table has primary key c1, c2 and c3.
Table is set with SALT_BUCKETS=12. Now it has 14 regions.
The table has a record with c1='a', c2='b', c3='c'
If Phoenix query is like:
select * from t where c2='b', it returns some results.

And the table is simple and has no index set up.

Did you try with updating table statistics, it may be because some times
table guideposts are out of sync
Below is the SQL to update table stats
Update statistics table
By default above executes asynchronously, hence it may take some time to
update depending on table size

Yes, that seems to be a trick, the issue is only associated a region.
What could be the causes of guidposts not updated?

There are few reasons - around corner cases , starting from a region-split
to any minor compactions during write process, general recommendation is to
not use guide posts for query processing - or - disable guideposts so the
consistency is guaranteed
