There are two schema's associated with a sstable writer: the sstable's schema (i.e. the schema of the table at the time when the sstable object was created), and the writer's schema (equal to the schema of the reader which is feeding into the writer). It's easy to mix up the two and break something as a result. The writer's schema is needed to correctly interpret and serialize the data passing through the writer, and to populate the on-disk metadata about the on-disk schema. The sstables's schema is used to configure some parameters for newly created sstable, such as bloom filter false positive ratio, or compression. The problem fixed by this patch is that the writer was wrongly creating the filter based on its own schema, while the layer outside the writer was interpreting it as if it was created with the sstable's schema. This patch forces the writer to pick the filter's parameters based on the sstable's schema instead.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
