Enable CouchDB in Hyperledger Fabric ... , but they are strongly recommended for performance. Thanks. Downloading fabric-couchdb docker images from the Hyperledger Docker Hub What is CouchDB Index? Exalate Connect. Create Asset. The performance, however, is dependent on some parameters and would, therefore, differ based on them. With Fabric v2.0, a new peer cache replaces many of these expensive lookups with fast local cache reads. Get Asset. The asset retrieval benchmark consists of evaluating getAsset gateway transactions for the fixed-asset smart contract deployed within LevelDB and CouchDB networks that uses a 2-of-any endorsement policy. Get your technical queries answered by top developers ! Hyperledger Fabric performance observations are obtained from testing smart contracts, driven by Fabric-SDK-Node clients through a series of benchmarks. Also, I have a couple of questions to the Fabric developers about its performance. CouchDB runs as a separate database process alongside the peer, therefore there are additional considerations in terms of setup, management, and operations. The use of Alpine-based docker images may reduce the amount of infrastructure required for the Fabric deployment; and the use of caching in the state database is good news for performance, as it minimizes the annoying delay in which we incur every time we use a GetState/PutState operation and we need to communicate with CouchDB to manage some data. How would you debug the issue? FAB-6421 Fabric performance improvements - 1.x. One of which is the ability to choose different databases to store blockchain data. Based on this I can conclude that Fabric Peer has problems with the CouchDB connection under the load. Privacy: Your email address will only be used for sending these notifications. This will result in the method being run on a single Hyperledger Fabric Peer and will not result in any interaction with the Orderer. I created simple nodejs app which interacts with the Fabric network using SDK and exposes HTTP API for load tests. Hyperledger Fabric is an enterprise-grade permissioned distributed ledger framework for developing solutions and applications. Hyperledger Fabric v1.1.0 network deployed using Cello on four c5.9xlarge (36vCPU) aws instances: Fabric channel configuration (all others parameters are the default): I performed tests for both CouchDB and LevelDB as a state database. INTRODUCTION Blockchain technology is increasingly becoming popular, with applications in various domains such as finance, real estate, supply chains, etc. My questions: What is the cause of this latency degradation? - hyperledger/fabric Empty Contract. Dates. I collected all useful information and want to share it with the HF community. Batch Get Asset. Hyperledger Fabric is build on a modular architecture that separates transaction processing and agreement (“chaincode”), transaction ordering, and transcation validation and commitment. I use official Fabcar chaincode (Golang implementation) for my tests. FAB-6804 Fabric CouchDB rich-query Performance. In a performance test using CouchDB, GetState by primary key can get 200 TPS, but rich query on an indexed field gets only 7 TPS. People. Query results: https://overload.yandex.net/101153. At ~1100 rps latency starts to increase. Created: 30/Oct/17 4:20 PM Updated: 20/Jul/18 6:48 PM Resolved: 14/Jul/18 5:08 AM. State database cache for improved performance on CouchDB — When using external CouchDB state database, read delays during endorsement and validation phases have historically been a performance bottleneck. It offers a unique approach to consensus that enables performance at scale while preserving privacy. Email me at this address if my answer is selected or commented on: Email me if my answer is selected or commented on, Hyperledger Fabric: A Distributed Operating System for Permissioned Blockchains, https://gist.github.com/krabradosty/9780cacc92fcdeaa0c36377a91727ade, https://gist.github.com/krabradosty/3810151b8e101d8279cc705aef22863e. Type: Sub-task Status: Closed (View Workflow) Priority: High . When submitting emptyContract gateway transactions, the interaction is recorded on the ledger. With Fabric v2.0, a new peer cache replaces many of these expensive lookups with fast local cache reads. For the past few months me and my team have been working on an extensive work of analyzing, understanding, and improving the performance of a Hyperledger Fabric in order to draw a set of performance best practice for the deployment of Fabric production networks. Performance Test of the Hyperledger Fabric, During trying to achieve the performance with Hyperledger Fabric which IBM team reported in their article. What plans does Fabric community have on improving the performance? I recently tested and compared the performance of Fabric between v2.0.1 and v2.1.0 using Caliper. Also peer001 prints a lot of similar error logs (not full output, just tiny part, I can share it with you if needed): A lot of error logs from the peer (again, not full output): There are no any errors from the blockchain, I just see latency degradation. Therefore transaction latency is quite low. XML Word Printable. Also, before looking for results you need to make sure that the load generator is not becoming a bottleneck. Export. Its modular and versatile design satisfies a broad range of industry use cases. Performance test (throughput in transactions/sec) for Ledger component through the ledger API, using CouchDB. CouchDB - max number of connections issue during stress test, FAB-3464 Hyperledger Fabric is the permissioned blockchain framework which belongs to the Hyperledger family. I was supposed to present this work first in a talk at the Hyperledger Global Forum in Phoenix, and on my return in a Hyperledger … With Hyperledger Fabric 2.0, a new peer cache replaces many of these expensive lookups with fast local cache reads. I've performed two kinds of tests with high load: query (requests via peer001 to the Fabric state when blockchain is empty) and insert (transactions within the blockchain). This app is stateless and can be easily scaled. Welcome to the second part of this series dedicated to performance best practices in Hyperledger Fabric.
