tool. First, pack the virus file with WinRAR, and then use Rising Antivirus assistant's "delete at next startup" to kill it.

Introduction: In many kV systems or distributed cache systems, routing policies are designed based on physical nodes. For example, consistent hash of Voldemort. each node in the ring corresponds to a physical machine in reality. For a simple and relatively independent kV system, it may be okay to deal with a large number of Kv application scenarios. However, in o

KV storage is ideal for business data that does not involve too much data-relational business relationships, while reducing the number of reads and writes to the disk, with better read and write performance than SQL database storage.

Relational databases often face challenges in Internet applications that store massive amounts of data: No quick hash search capability for key-value; The access interface does not support HTTP; The TPS for reading and writing is not high enough; Since Google's bigtable, key-value databases have attracted the attention of more and more developers. There are more and more KV-structured databases in Internet projects. With the incr

Where master server does some management data storage and distributed scheduling, the actual distributed data storage and read and write operations are done by the tablet server, while Leveldb can be understood as a simplified version of the tablet server. LEVELDB has the following characteristics: First of all, Leveldb is a persistent storage kv system, unlike Redis this type of memory kv s
