When it does so, it sets a maximum duration for it to complete work on the item as a part of the create/update operation. Ideally, it will use the CMS’s clock to do this. The RFS Worker is assumed to have a lease on that work item until that duration expires. If the work is not completed in that time, the RFS Worker will create a successor work item that defines the remaining work and mark the current work item as finished. As a specific example, an RFS Worker queries the CMS to find an Elasticsearch Shard to migrate to the target cluster. The CMS returns a record corresponding to a specific Elasticsearch Shard’s progress that either has not been started or has an expired work lease, and the RFS Worker performs an optimistic update of its timestamp field, setting it (hypothetically) for 5 hours from the current time (according to the CMS’s clock). -RFS Workers regularly polls the CMS to see if their current work item’s lease has expired (according to the CMS’s clock); if they find it has expired, they kill themselves and allow an outside system to spin up a replacement RFS Worker. Similarly, the RFS Scaler will check for expired work items and ensure that any RFS Workers associated with them have been reaped. +RFS Workers regularly polls the CMS to see if their current work item’s lease has expired (according to the CMS’s clock); if they find it has expired, they kill themselves and allow an outside system to spin up a replacement RFS Worker. The process of finding the optimal initial work lease duration will be data driven based on actual usage statistics. The CMS will contain the duration of each work item after a RFS operation finishes, which can be used to iteratively improve the initial “guess”. Each RFS Worker is responsible for setting the duration for work items it attempts to acquire a lease for. ### One work lease at a time -An RFS Worker retains no more than a single work lease at a time. If the work item associated with that lease has multiple steps or components, the work lease covers the completion of all of them as a combined unit. As a specific example, the RFS Worker that wins the lease to migrate an Elasticsearch Shard is responsible for migrating every Document in that Shard. +An RFS Worker retains no more than a single work lease at a time.

As a specific example, the RFS Worker that wins the lease to migrate an Elasticsearch Shard is responsible for migrating every Document in that Shard starting at the given doc num (or at the beginning if not specified). ### Work lease backoff -When an RFS Worker acquires a work item, it increments the number of attempts that have been made to finish it. The RFS Worker increases its requested work lease duration based on the number of attempts. If the number of attempts passes a specified threshold, the RFS Worker instead marks the work item as problematic so it won’t be picked up again. +When an RFS Worker acquires a work item, it increments the lease time exponent that will be used on the subsequent attempt.

The reasoning for this policy is as follows. -The unit of work for an RFS Worker migrating Elasticsearch Documents is an Elasticsearch Shard, not an Elasticsearch Document. If an RFS Worker dies unexpectedly while moving the Elasticsearch Documents in an Elasticsearch Shard, it would be hard to reliably track exactly which had been successfully moved such that another RFS Worker could resume at the correct position. We will instead simplify the design by just starting the Elasticsearch Shard over from the beginning and overwriting any partial work. +The pending work items are the remaining docs for each Elasticsearch Shard. The RFS Workers have a consistent view of the position of a document within the entire shard. If a lease is about to expire and a shard has not been fully migrated, the RFS Workers use the latest continuous migrated doc number to reduce the duplicate work a successor work item has. ## How the RFS Worker works diff --git a/RFS/src/main/java/org/opensearch/migrations/bulkload/worker/DocumentsRunner.java b/RFS/src/main/java/org/opensearch/migrations/bulkload/worker/DocumentsRunner.java index c39d75609..df8406c55 100644 --- a/RFS/src/main/java/org/opensearch/migrations/bulkload/worker/DocumentsRunner.java +++ b/RFS/src/main/java/org/opensearch/migrations/bulkload/worker/DocumentsRunner.java @@ -85,7 +85,7 @@ public CompletionStatus migrateNextShard( } }, new IWorkCoordinator.WorkAcquisitionOutcomeVisitor<>() { @Override - public CompletionStatus onAlreadyCompleted() throws IOException { + public CompletionStatus onAlreadyCompleted() { return CompletionStatus.NOTHING_DONE; } @@ -93,23 +93,23 @@ public CompletionStatus onAlreadyCompleted() throws IOException { public CompletionStatus onAcquiredWork(IWorkCoordinator.WorkItemAndDuration workItem) { var docMigrationCursors = setupDocMigration(workItem.getWorkItem(), context); var latch = new CountDownLatch(1); - var finishScheduler = Schedulers.newSingle( "finish-scheduler"); + var finishScheduler = Schedulers.newSingle( "workFinishScheduler"); var disposable = docMigrationCursors .subscribeOn(finishScheduler) - .doFinally(s -> finishScheduler.dispose()) + .doFinally(s -> finishScheduler.dispose()) .takeLast(1) - .subscribe( lastItem -> {}, - error -> log.atError() - .setCause(error) - .setMessage("Error prevented all batches from being processed") - .log(), - () -> { - log.atInfo().setMessage("Reindexing completed for Index {}, Shard {}") - .addArgument(workItem.getWorkItem().getIndexName()) - .addArgument(workItem.getWorkItem().getShardNumber()) - .log(); - latch.countDown(); - }); + .subscribe(lastItem -> {}, + error -> log.atError() + .setCause(error) + .setMessage("Error prevented all batches from being processed") + .log(), + () -> { + log.atInfo().setMessage("Reindexing completed for Index {}, Shard {}") + .addArgument(workItem.getWorkItem().getIndexName()) + .addArgument(workItem.getWorkItem().getShardNumber()) + .log(); + latch.countDown(); + }); // This allows us to cancel the subscription to stop sending new docs // when the lease expires and a successor work item is made. // There may be in-flight requests that are not reflected in the progress cursor From 178fe55043ab22410a512cd0ad238bfc8bf65253 Mon Sep 17 00:00:00 2001 From: Andre Kurait Date: Thu, 5 Dec 2024 15:12:53 -0600 Subject: [PATCH 19/19] Fix WorkCoordinatorTest Signed-off-by: Andre Kurait --- .../bulkload/workcoordination/WorkCoordinatorTest.java | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) diff --git a/RFS/src/test/java/org/opensearch/migrations/bulkload/workcoordination/WorkCoordinatorTest.java b/RFS/src/test/java/org/opensearch/migrations/bulkload/workcoordination/WorkCoordinatorTest.java index e268498ae..d645c0ed8 100644 --- a/RFS/src/test/java/org/opensearch/migrations/bulkload/workcoordination/WorkCoordinatorTest.java +++ b/RFS/src/test/java/org/opensearch/migrations/bulkload/workcoordination/WorkCoordinatorTest.java @@ -260,7 +260,7 @@ public void testAddSuccessorWorkItemsSimultaneous() throws Exception { try (var workCoordinator = new OpenSearchWorkCoordinator(httpClientSupplier.get(), 3600, "docCreatorWorker")) { Assertions.assertFalse(workCoordinator.workItemsNotYetComplete(testContext::createItemsPendingContext)); for (var i = 0; i < NUM_DOCS; ++i) { - final var docId = "R" + i + "__0__0"; + final var docId = "R__0__" + i; workCoordinator.createUnassignedWorkItem(docId, testContext::createUnassignedWorkContext); } Assertions.assertTrue(workCoordinator.workItemsNotYetComplete(testContext::createItemsPendingContext)); @@ -273,7 +273,7 @@ public void testAddSuccessorWorkItemsSimultaneous() throws Exception { int finalI = i; allFutures.add( CompletableFuture.supplyAsync( - () -> getWorkItemAndCompleteWithSuccessors(testContext, "successor_test_" + finalI, seenWorkerItems, expiration, true, NUM_SUCCESSOR_ITEMS), + () -> getWorkItemAndCompleteWithSuccessors(testContext, "successor__0__" + finalI, seenWorkerItems, expiration, true, NUM_SUCCESSOR_ITEMS), executorService ) ); @@ -418,7 +418,8 @@ private String getWorkItemAndCompleteWithSuccessors( ); ArrayList successorWorkItems = new ArrayList<>(); for (int j = 0; j < numSuccessorItems; j++) { - successorWorkItems.add(workItemId + "__0__" + j); + // Replace "__" with "_" in workerId to create a unique name + successorWorkItems.add(workItemId.replace("__", "_") + "__0__" + j); } try (var workCoordinator = new OpenSearchWorkCoordinator(httpClientSupplier.get(), 3600, workerName)) { workCoordinator.createSuccessorWorkItemsAndMarkComplete(
