DynamoDB normalizes Number values, so different string representations of the same number (e.g., "1000" vs "1e3") should be treated as the same value in all contexts. In Alternator this is true in most cases, thanks to implicit normalization in Decimal `to_string()` function. However this is fragile - and in fact this function should be fixed due to OOM vulnerability in CQL use (#8002). This patch adds tests that should prevent regression in cases that work currently. Unfortunately not all contexts work currently - mainly the HASH keys are not normalized and backend handles them by byte representation. Added test replicate this incorrect behaviour All added tests pass with DynamoDB, with one exception: weirdly DynamoDB doesn't recognise unnormalized numbers in BatchGetItem as duplicate keys.

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.
