Just answer just a friend about HotDB What are the advantages, also here today to share with you below:
Distributed Transaction database HotDB product after grinding more than eight years, the current financial industry cooperation with more than 50 customers to participate in a number of national key projects, "stable and reliable" product features fully meet the financial and industrial grade requirements
In product performance and function has the absolute advantage:
high throughput precise and predictable disaster recovery across data centers double live
1. To achieve functional data flow control and data synchronization application.
2. The data synchronization required to achieve at least 100,000 TPS, with no large change transaction database table structure and a case where the delay within three seconds.
3. Support multi-line redundancy, the same packet can be transmitted simultaneously, the terminal will automatically select and meet the requirements of the earliest arriving packets on multiple lines.
3. Support network congestion control algorithm against cross-data center network packet loss and network delay variation, and therefore avoid the occurrence of a substantial decline in the efficiency of data synchronization.
AI intelligent algorithm to optimize data slice
• default configuration data fragmentation rules, data fragmentation in accordance with the master key or a unique index, or direct vertical slice
• Link-pressure measurement or business operations, to obtain the current traffic system, data slice integrated assessment, the time-consuming database operations and distribution
• intelligent deduce the best solution, by accessing the data collection based on intelligent algorithms to automatically calculate the three data fragmentation and to give the best recommendation
• best online application, by online adjustment data fragmentation rules function, without affecting the business
case of access, automatically applies the optimum data slicing scheme
Breakthrough distributed consensus protocol restrictions
breakthrough Raft / Paxos protocol more than half of compute nodes in a cluster can not appear to limit operation, only the ability to compute node can still provide continuous data services down to the hot Pu database HotDB achieved, providing higher compute node availability
