René Cordier updated JAMES-3010:
--------------------------------
Description:
Introduce a `BlobExistenceTester` API within blob-objectstorage:
{code:java}
interface BlobIdExistantTester {
Mono<Boolean> exists(ObjectStorageBucketName bucketName, BlobId blobId);
Mono<Void> persist(ObjectStorageBucketName bucketName, BlobId blobId);
Mono<Void> delete(ObjectStorageBucketName bucketName, BlobId blobId);
Mono<Void> deleteBucket(ObjectStorageBucketName bucketName);
}
{code}
Create a `FakeBlobExistenceTester` that always returns false.
Create a `MemoryBlobExistenceTester` and the related tests.
Create a `CassandraBlobExistenceTester` and the related tests.
Ensure `ObjectStorageBlobStore`:
- Don't persist small blobs that already exist
- Don't attempt to rename (copy) big blobs that already exist - deleting the
intermediary blob supplied is enough - and faster.
when Cassandra is down, just store it as normal
Propose a proof of concept regarding these changes.
