Evgenii Stratonikov b5bcf90fa1 [#1186] engine: Read object directly from blobstor in case of conflicts
Metabase is expected to contain actual information about objects stored
in shard. If the object is present in metabase but is missing from
blobstor, peform an additional attempt to fetch it directly without
consulting metabase. Such a situation is unexpected, so error counter
is increased for the shard which has the object in the metabase. We
don't increase error counter for the shard which has the object in
blobstor, because some garbage can be expected there. In this
implementation there is no overhead for objects which are really
missing, i.e. are not present in any metabase.

NeoFS

NeoFS is a decentralized distributed object storage integrated with the NEO Blockchain.


Report GitHub release (latest SemVer) License

Overview

NeoFS Nodes are organized in peer-to-peer network that takes care of storing and distributing user's data. Any Neo user may participate in the network and get paid for providing storage resources to other users or store his data in NeoFS and pay a competitive price for it.

Users can reliably store object data in the NeoFS network and have a transparent data placement process due to decentralized architecture and flexible storage policies. Each node is responsible for executing the storage policies that the users select for geographical location, reliability level, number of nodes, type of disks, capacity, etc. Thus, NeoFS gives full control over data to users.

Deep Neo Blockchain integration allows NeoFS to be used by dApp directly from NeoVM on the Smart Contract code level. This way dApps are not limited to on-chain storage and can manipulate large amounts of data without paying a prohibitive price.

NeoFS has native gRPC API and popular protocol gates such as AWS S3, HTTP, FUSE and sFTP allowing developers to integrate applications without rewriting their code.

Supported platforms

For now we only support GNU/Linux on amd64 CPUs with AVX/AVX2 instructions. More platforms will be officially supported after '1.0' release.

Latest version of neofs-node works with neofs-contract v0.13.0.
