Compaction group can be defined as a set of files that can be compacted together. Today, all sstables belonging to a table in a given shard belong to the same...
What's contained in this series: - Refactored compaction tests (and utilities) for integration with multiple groups - The idea is to write a new class of tests that will stress...
It might happen that multiple tablets co-habit the same shard, so we want load-and-stream to jump into a new streaming session for every tablet, such that the receiver will have...
While playing with ignore-msb-bits param, there were lots of variance in node overcommit result caused by the rng picking a different seed every run. Possibly confusing an user who expects...
That will require adding code to parse Scylla metadata component, where the run identifier lives. Run identifier is important for understanding the layout of SSTables when ICS is used.
tool is important to verify which sstables are blocking the deletion of an expired sstable, but when running it, it fails as follow: Exception in thread "main" java.lang.IncompatibleClassChangeError: Found class...
Retrieval of tablet stats must be serialized with mutation to token metadata, as the former requires tablet id stability. If tablet split is finalized while retrieving stats, the saved erm,...
sstables: Fix incremental_reader_selector (for range reads) with tablets incremental_reader_selector is the mechanism for incremental comsumption of disjoint sstables on range reads. tablet_sstable_set was implemented, such that selector is efficient with...
that intrusive list was added for making it easy to iterate through compaction groups (in range based loop). but it's fragile as we need to be very careful on removing...
