Alex Petrov updated CASSANDRA-15778:
------------------------------------
Status: Patch Available (was: In Progress)
I think I have a patch I think solves the problem without introducing breaking
changes:
|[circleci|https://circleci.com/gh/ifesdjeen/cassandra/tree/15778-3.0]|[3.0
patch|https://github.com/apache/cassandra/compare/trunk...ifesdjeen:15778-3.0?expand=1]|
It does the following things:
* makes {{EmptyType}} restrictions slightly stricter withouot changing
semantics. Just make sure we can not write values with empty type.
* changes {{LegacySchemaMigrator}}, allowing to start a 3.0 node during
upgrade with {{-D cassandra.init_dense_table_compact_value_as_bytes=true}},
which would initialize a dense table compact value as {{ByteType}}. It will be
initialized as {{EmptyType}} by default.
* improves an error message in {{EmptySerializer}} for anyone who have faced
written data in the column that was supposed to be empty, referring them here.
* since we initialize with {{EmptyType}} by default, in case someone has
proceeded to upgrade their nodes withouot even testing an upgrade out (and
being able to just start upgrade with an aforementioned flag), allow {{ALTER
TABLE ALTER TYPE}} _only_ from {{EmptyType}} to {{BytesType}} and _only_ for a
dense table.
We should not change compact storage behaviour to suddenly reveal a
{{BytesType}} column for a huge userbase. Instead, we help out anyone who may
have written values with Thrift: either to _prevent_ seeing this issue (which
is ideal), or to _quickly fix_ it after upgrade. Schema changes won't propagate
accross versions, but they only need to propagate to 3.0 nodes only anyways.
