* ci: add crash, restart, multi-region and drop cells to the S3 WAL benchmark Extend the object store WAL S3 benchmark beyond one load per configuration: - Inputs for a full image reference, the configurations to run (R0 adds Raft Engine with the standalone default sync_write = false), extra environment for every server container, a restart after each load, and a JSON list of named cell groups that override those inputs. - Restart cells SIGKILL the loaded server, restart it on the same prefix and data home, and time /health, the first correct count and the log store recovery; min_objects fails a cell that left too few objects indexed. - Crash groups write striped 1000-row batches from several writers, kill the server at a random point, restart it and check every acknowledged batch against the table (durable: present exactly once; enqueued: no duplicate, no partial batch, losses counted). A pinned variant keeps one row of a second table unflushed and samples the indexed objects while it runs. - Idle windows scrape the server before and after a quiet period. - A load group may split the loaded table into equal event_time ranges, so every batch writes to every region, and checks that each region took rows. - Drop groups write a table, drop it, kill and restart the server, then write and flush another table and wait for the dropped table's objects to be collected. - The summary adds WAL traffic, objects per second, mean object size, entries and appends per object, S3 requests per operation, server and host CPU, the loader's own request latency, rows per region, crash cycles, and each restart's replay per region from the server log. Signed-off-by: jeremyhi <fengjiachun@gmail.com> * ci: report the object sequences a replay spans instead of objects replayed The width of a region's replayed entry range counts every object sequence in it, including objects that hold no entry of the region and are skipped, so the summary labels it as a span. Signed-off-by: jeremyhi <fengjiachun@gmail.com> * ci: fail a crash cycle that loses a batch an earlier restart recovered The oracle accepted every missing acknowledged batch in the enqueued mode, so a batch that one restart recovered and a later restart no longer found passed. Every cycle keeps what its restart found, and a cycle now fails in either mode unless every batch an earlier restart recovered is still present, so only the current cycle's backlog that was not durable at its kill may be missing. Signed-off-by: jeremyhi <fengjiachun@gmail.com> * ci: keep the pinned WAL pinned and label OpenDAL operations as such The pin table inherited the engine's 10-minute auto flush, so a longer pinned cycle could flush its row and release the WAL before the kill. It now sets its own auto_flush_interval of one day, longer than any crash group can run, and a pinned cycle fails unless its indexed objects never fall while it runs. The summary's request counts come from opendal_operation_duration_seconds, which counts OpenDAL calls rather than HTTP requests (a paginated list or a multipart write is one operation), so the fields and columns now say S3 operations. Signed-off-by: jeremyhi <fengjiachun@gmail.com> * ci: check a pinned cycle's retention by the collected-object counter Net growth of the indexed objects can hide collection, and short cycles take no periodic sample, so a pinned cycle now fails unless deleted_objects_total is the same in the scrape before its writers start and in the one before the kill, both of the same server process. The operation columns name OpenDAL. Signed-off-by: jeremyhi <fengjiachun@gmail.com> * ci: let a pinned cell collect only the objects below its pin The first write after a start lets the store collect the empty start object asynchronously, so a deletion after a cycle's baseline does not mean the pin let go. A pinned cell now scrapes the server before it writes the pin row and fails only once its servers together have collected more objects than were indexed then, counting the first server from that scrape and every restarted one from its start. Signed-off-by: jeremyhi <fengjiachun@gmail.com> * ci: test that a pinned cell's allowance spans its server restarts Two servers that each collect fewer objects than lie below the pin but more together now fail the cell in the second cycle.
