HEAD: https://github.com/scylladb/seastar/commit/5b34dfe230a8c0d816ebf5260e88af92e80f9bdd *Description* We want to improve auto-detection for very large machines for which a single physical core is not enough for IRQs handling (48 vCPUs+).
HEAD: 5b34dfe230a8c0d816ebf5260e88af92e80f9bdd *Description* We want to stop using `--mode` parameter and switch to `irq_cpu_mask` instead. We should continue supporting `--mode`/`mode` as an input for backward compatibility but stop generating it...
**The Problem** Today the only I/O mode seastar supports is Direct I/O. The main advantage is that we can use all that memory that would otherwise be needed for the...
Add a framework to deprecate parameters (ignore given values) and then use it to deprecate --write-back-cache parameter.
Enable RPS on all requested CPUs (or all present CPUs if cpu_mask is not given). This makes networking more efficient for applications that are bound to IRQ CPUs. Fixes #818...
HEAD: 0d250d15ace37973a1fbf449cb06adbcc5f8a9da *Description* Changing a value of `/sys/block/.../queue/write_cache` is bogus and dangerous because it doesn't change the behavior of the underlying HW and only changes the way kernel "thinks" the...
"Tau" is a parameter of an I/O scheduler which value can significantly improve the scheduler performance or make it worse depending on a specific workload. In particular "tau" is a...
HEAD: 4c93a694b7928c20bdb86b77dea5c50cd71195a0 *Description* Add asynchronous REST API for decommissioning and removing a node and checking the status of the corresponding async task. Ref * https://github.com/scylladb/scylladb/issues/9809 * https://github.com/scylladb/scylladb/issues/7742
*Installation details* HEAD: 961b9e8390236a1ac288fe8df15f1e698ade9a81 *Description* Add a REST API to check the status of the currently running `cleanup` job similarly to a `/storage_service/active_repair/` for repairs (see a usage example here:...
*Installation details* HEAD: 961b9e8 *Description* Today APIs for issuing (major) compactions are blocking. This makes it rather impractical for automated tool because it requires to keep the corresponding TCP connection...
