Merged patch series from Piotr Sarna: This series allows reading rows from Scylla's system tables via alternator by using a virtual interface. If a Query or Scan request intercepts a table name with the following pattern: .scylla.alternator.KEYSPACE_NAME.TABLE_NAME, it will read the data from Scylla's KEYSPACE_NAME.TABLE_NAME table. The interface is expected to only return data for Scylla system tables and trying to access regular tables via this interface is expected to return an error. This series comes with tests (alternator-test, scylla_only). Fixes #6122 Tests: alternator-test(local,remote (to verify that scylla_only works) Piotr Sarna (5): alternator: add fallback serialization for all types alternator: add fetching static columns if they exist alternator: add a way of accessing system tables from alternator alternator-test: add scylla-only test for querying system tables docs: add an entry about accessing Scylla system tables alternator-test/test_system_tables.py | 61 +++++++++++++++++++++++++++ alternator/executor.cc | 38 ++++++++++++++++- alternator/executor.hh | 1 + alternator/serialization.cc | 11 +++-- docs/alternator/alternator.md | 15 +++++++ 5 files changed, 122 insertions(+), 4 deletions(-) create mode 100644 alternator-test/test_system_tables.py
