I always feel a waste (at least I feel uncomfortable ...) Therefore, this method is not recommended.
I personally think that if the associated query can solve the problem, I can use the connection query.
If you want to use it, pay attention to other query conditions and try to use indexes to avoid operations such as range variables and uncertain judgment.
The purpose is to reduce the time for a single operation, so even if the for all entries is divi

working in a mixed network environment, this format ensures compatibility between the IPV6 node and the IPV4 node. These two types of IPV6 addresses use this optional format: IPV6 Address through IPV4 mappingThis type of address is used to represent the IPV4 node as an IPv6 address. It allows IPV6 applications to communicate directly with IPV4 applications. For example, 0:0:0:0:0:ffff:192.1.56.10 and:: ffff:192.1.56.10/96 (Short form).IPV6 Address for compatible IPV4This type of address is used

"The heap is just one part of the JVM and there is an interpreter; The interpreter increases the maximum heap size by 20% to 50% in process memory usage depending on the operating system, JVM, and heap size." Therefore, for this customer, for a 32-bit JVM with a maximum heap size of 768 MB, its hardware and software configuration consumes about 950MB of memory, and its corresponding 64-bit JVM requires approximately 1.9GB of memory, and there is no memory available to the operating system
