Heap MemoryThe heap in Java is the largest memory space managed by the JVM and is primarily used to store instance objects of various classes.In Java, the heap is divided into two different areas: the New Generation (young), the old generation (older). The New Generation (young) is divided into three regions:Eden, from Survivor, to Survivor.The purpose of this pa

1 Introduction
Telecom operators around the world are facing tremendous pressure from the constant technological innovation and the constant pursuit of communication methods by users. In particular, the profit of the traditional main business PSTN of fixed network operators is declining year by year. On the one hand, the free services of instant communication, P2P voice and streaming media such as MSN on the Internet have greatly attracted the attention of broadband Internet users, large-scale c
The Next Generation Network Based on IP transmission technology also puts forward new requirements for the core equipment routers. For example, how to handle data congestion, ensure transmission quality, ensure QoS of various services, realize direct communication between multiple types of terminals, and quickly and conveniently increase value-added services and solve address shortage issues. The solution to these problems will surely bring about a co

The primary key is generated by an external program and does not involve hibernate.
2) HiLo(High/low)
Use a high/low level algorithm to efficiently generate long, short, or Int type identifiers. Specify a table and field (hibernate_unique_key and next by default) as the source of high value. The identifier generated by the high/low algorithm is unique only in a specific database. Do not use this generator in the connection obtained by using JTA or the conne
