In pull request #26960 there was some discussion about what is the valid form of ExclusiveStartKey, and whether we need to allow some "non-standard" uses of it for scan over system tables (which aren't real Alternator tables and may have multiple key columns, something not possible in normal Altenrator tables). This made me realize our tests for what is allowed - and what is not allowed - in ExclusiveStartKey - are very sparse and don't cover all the cases that are possible in Scan and Query, in base tables and in GSIs. So this small series attempts to increase the coverage of the tests for ExclusiveStartKey to make sure we are compatible with DynamoDB and also that we don't regress in #26960. The new tests reproduce a previously unknown error-path issues, #26988, where in some cases DynamoDB considers ExclusiveStartKey to be invalid but Alternator erronously accepts. Fortunately, we didn't find any success-path (correctness) bugs. Closes scylladb/scylladb#26994 * github.com:scylladb/scylladb: test/alternator: tests for ExclusiveStartKey in GSI test/alternator: more tests for ExclusiveStartKey in Scan test/alternator: more tests for ExclusiveStartKey in Query

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.
