PRAGMA TablePathPrefix for ALTER TOPIC

[apervushin]

Hi,

We use some kind of migration manager to apply DDL migrations to YDB. And we've faced with an issue during the following migration:

PRAGMA TablePathPrefix = '/database/path/to/tables';

ALTER TABLE `my_table` ADD CHANGEFEED `my_feed` WITH (
    FORMAT = 'JSON',
    MODE = 'UPDATES',
    RETENTION_PERIOD = Interval("P7D")
);

ALTER TOPIC `my_table/my_feed` ADD CONSUMER `my_consumer`;

ALTER TOPIC migration fails due to TablePathPrefix does not work for this command (only for ALTER TABLE). As a result we created:

• /database/path/to/tables/my_table - table
• /database/path/to/tables/my_table/my_feed - topic

But ALTER TOPIC trying to find /database/my_table/my_feed instead of /database/path/to/tables/my_table/my_feed.

Is it possible to make PRAGMA TablePathPrefix affect ALTER TOPIC as well or add something like PRAGMA TopicPathPrefix?
