org.apache.cassandra.db.rows.RangeTombstoneMarker.Merger is allocated on demand
Optional usage in org.apache.cassandra.db.rows.UnfilteredRowIteratorWithLowerBound is replaced with a boolean field
Double in org.apache.cassandra.io.util.CompressedChunkReader#getCrcCheckChance - specialized supplier is used to avoid boxing
Stack - adjust default from 5 to 6 to avoid extra resizings in org.apache.cassandra.db.transform.Stack#resize
EnumSet for CL guardrail in SelectStatement - add a condition to allocate it only if the guardrail is enabled
EnumSet in ResultMetadata - replace it with plain int flags

Validate snapshot names
...
The validation of snapshot names is turned off by default.
It is controlled by system property cassandra.snapshot.validation which is by default
set to false except 7.0 branch.
When the validation is turned on, the allowed characters are AWS safe characters together
with "+" character. A user can not specify any path separators in snapshot names even if
the validation as such is turned off.

Reduce memory allocations in row merge logic
...
org.apache.cassandra.utils.MergeIterator.Candidate - has Comparator field which is the same for all Candidates under an MergeIterator instance, we can move the field to MergeIterator level. Candidate is 4.8% of all allocations and we can save 20% (~1% of all allocations) of it for JDK 21 with compressed references on.
switch from ArrayList to array in org.apache.cassandra.db.rows.Row.Merger
The ArrayList iterator costs 0.72% and BulkIterator.Adapter costs 0.35%. So, in total we can save here ~1% of total allocations.
