Hmily is a high-performance, zero penetration, financial-level distributed transactions solution. At present, it mainly provides support for flexible transactions, including
TAC (in which, it will automatically generate rollback SQL) schemes, and
XA and more schemes will be supported in the future.
High reliability : It supports abnormal transaction rollback and transaction overtime abnormal recovery to prevent transaction suspension in distributed scenarios.
Ease of use : It provides zero penetration
Spring-Namespaceschemes to integrate with business systems quickly.
High performance : Decentralized design, fully integrated with business systems, and naturally supports cluster deployment.
Observability : Performance monitoring of multiple metrics will be collected by Metrics, performance metrics is able to display in admin management system.
Multiple RPC Framework support : It supports well-known RPC frameworks such as
Multiple log store medium support : It supports many mediums as log store, such as
Complex business scene : It supports transaction around nested RPC calls.
JDKversion must be
TCCmode, you must use a
RPCframework, such as:
TACmode, you must use relational databases, such as:
When using the
TCC mode, you should provide three methods:
cancel according to your business requirements,
cancel methods should be implemented by yourselves, the framework is only responsible for calling them to achieve transaction consistency.
When using the
TAC mode, you must use a relational database for business operations, and the framework will automatically generate a
When the business is abnormal, the
rollback SQL will be executed to achieve transaction consistency
Hmily is a flexible distributed transaction solution that provides
It can be easily integrated by business with zero intrusion and rapid integration.
In terms of performance, log storage is asynchronous (optional) and uses asynchronous execution, without sacrificing business methods.
It was previously developed by myself personally, and it is currently restarted at JD Digital Technique Group, and it will become JD Digital Technique Group’s distributed transaction solution in the future.
