From 505fd5189b0802013fa03e978d62fc70ca0c1337 Mon Sep 17 00:00:00 2001 From: Sven Fillinger Date: Fri, 28 Aug 2026 09:24:07 +0200 Subject: [PATCH 01/33] Add storage provider abstraction architecture This document outlines the architecture for abstracting storage providers in the data download server to support multiple backends (NFS, S3, openBIS DSS). Key features: - Clean StorageProvider interface with multiple access patterns - Provider registry for dataset-to-provider mapping - Gradual migration strategy with parallel implementation - Backward compatible API endpoints - Simplified architecture removing producer-consumer complexity The architecture enables: - Direct file I/O for NFS (better performance) - Pre-signed URLs for S3 (client direct access) - Adapter pattern for existing openBIS code (low risk) - Configurable per-user limits and retry strategies - Future-proof design for additional storage backends Implementation plan includes 6 phases over 10 weeks with detailed deliverables, testing strategy, and risk mitigation. --- provider-abstraction-architecture.md | 580 +++++++++++++++++++++++++++ 1 file changed, 580 insertions(+) create mode 100644 provider-abstraction-architecture.md diff --git a/provider-abstraction-architecture.md b/provider-abstraction-architecture.md new file mode 100644 index 0000000..63a8d3b --- /dev/null +++ b/provider-abstraction-architecture.md @@ -0,0 +1,580 @@ +# Storage Provider Abstraction Architecture + +## Overview + +This document describes the architecture for abstracting storage providers in the data download server.

Implement OpenBisStorageProvider adapting the legacy MeasurementDataProvider (openBIS) to this contract with byte-range support. * docs: declare thrown exceptions on storage interfaces Add throws clauses to the interface methods so callers can see the failure modes of each operation. Exceptions remain unchecked, so the declarations are informational and do not force handling. * perf: cache openbis file listing in adapter Multiple file and byte-range requests on the same dataset each triggered an openBIS listFiles call. Cache the path-sorted listing per dataset for a short TTL (default 30s) so requests issued close together share one listing. Datasets change very seldomly, so the cache stays valid. * refactor: drop byte-range support from openbis adapter OpenBisStorageProvider no longer implements ByteRangeProvider; it serves whole files only. Range handling is left to providers that support it natively (NFS, S3). * feat: model all RFC 9110 byte-range forms Replace the start/end record with a sealed ByteRange covering int-range (both bounds), open-ended int-range and suffix-range. Add resolve(fileSize) to compute concrete bounds and a ByteRangeParser for Range header values. Byte offsets are inclusive per RFC 9110 section 14.1.2. * refactor: rename ByteRange.Resolved to ResolvedRange Clarify that resolve() yields a concrete range, not an opaque result. ---------

This enables high-performance NFS-based downloads while maintaining openBIS metadata richness (checksums, timestamps, file ordering). --- .../openbis/OpenBisNfsStorageProvider.java | 248 ++++++++++++++++++ .../OpenBisNfsStorageProviderTest.java | 215 +++++++++++++++ .../rest/storage/ProviderRegistryConfig.java | 25 +- .../src/main/resources/application.properties | 14 +- .../ProviderRegistryConfigOpenBisNfsTest.java | 114 ++++++++ 5 files changed, 613 insertions(+), 3 deletions(-) create mode 100644 openbis-connector/src/main/java/life/qbic/data_download/openbis/OpenBisNfsStorageProvider.java create mode 100644 openbis-connector/src/test/java/life/qbic/data_download/openbis/OpenBisNfsStorageProviderTest.java create mode 100644 rest-api/src/test/java/life/qbic/data_download/rest/storage/ProviderRegistryConfigOpenBisNfsTest.java diff --git a/openbis-connector/src/main/java/life/qbic/data_download/openbis/OpenBisNfsStorageProvider.java b/openbis-connector/src/main/java/life/qbic/data_download/openbis/OpenBisNfsStorageProvider.java new file mode 100644 index 0000000..0dedf0d --- /dev/null +++ b/openbis-connector/src/main/java/life/qbic/data_download/openbis/OpenBisNfsStorageProvider.java @@ -0,0 +1,248 @@ +package life.qbic.data_download.openbis; + +import static java.util.Objects.requireNonNull; + +import java.io.IOException; +import java.io.InputStream; +import java.nio.channels.Channels; +import java.nio.channels.FileChannel; +import java.nio.file.Files; +import java.nio.file.Path; +import java.nio.file.StandardOpenOption; +import java.time.Duration; +import java.time.Instant; +import java.util.Comparator; +import java.util.List; +import java.util.Map; +import java.util.Optional; +import java.util.concurrent.ConcurrentHashMap; +import life.qbic.data_download.measurements.api.FileInfo; +import life.qbic.data_download.measurements.api.MeasurementDataProvider; +import life.qbic.data_download.measurements.api.MeasurementId; +import life.qbic.data_download.storage.ByteRange; +import life.qbic.data_download.storage.ByteRangeProvider; +import life.qbic.data_download.storage.DataFile; +import life.qbic.data_download.storage.FilePathProvider; +import life.qbic.data_download.storage.StorageProvider; +import life.qbic.data_download.storage.exception.DatasetNotFoundException; +import life.qbic.data_download.storage.exception.StorageFileNotFoundException; +import life.qbic.data_download.storage.exception.StorageProviderException; + +/** + * A hybrid storage provider that uses openBIS for metadata (file list, order, checksums, timestamps) + * but streams file content directly from the mounted filesystem via NIO. + * + *

This caused byte range requests to fail with 416 errors when the metadata size didn't match the actual file size. Now the provider reads the actual file size from the filesystem using Files.size() for: - listFiles() - returns correct sizes in file listings - getFile() - uses actual size for range resolution - getFileMetadata() - returns correct size in metadata This ensures resumable downloads work correctly with proper byte range support.

Consolidate the whole project onto one version defined once in the root pom: - root declares ${revision} with 1.3.0 - child modules no longer declare their own ; they inherit the parent and reference it via ${revision} - inter-module dependencies use ${project.version} so they stay in sync Update the release workflow to bump the revision property (versions:set would have overwritten the ${revision} expression); set-property keeps the central property as the single source of truth.
