* feat: support alter from primary_key to flat Signed-off-by: evenyag <realevenyag@gmail.com> * chore: alter flat to primary_key Signed-off-by: evenyag <realevenyag@gmail.com> * feat: change default_experimental_flat_format to true Signed-off-by: evenyag <realevenyag@gmail.com> * feat: compute channel size from splitted batch size Signed-off-by: evenyag <realevenyag@gmail.com> * test: add tests for split and channel size Signed-off-by: evenyag <realevenyag@gmail.com> * fix: always set sst_format from manifest on region open sanitize_region_options did not set options.sst_format when the default (PrimaryKey) matched the manifest value, leaving it as None after reopen. This caused the alter format change to appear lost. Signed-off-by: evenyag <realevenyag@gmail.com> * test: fix tests Signed-off-by: evenyag <realevenyag@gmail.com> * test: show create table after alteration Signed-off-by: evenyag <realevenyag@gmail.com> * refactor!: rename default_experimental_flat_format to default_flat_format The flat format is no longer experimental. Remove "experimental" from the config field name, doc comments, and all references.
