A SequenceInputStream represents the logical concatenation of other input streams. It starts out with an ordered collection of input streams and reads from the first one until end of file is reached, whereupon it reads from the second one, and so on, until end of file is reached on the last of the contained input streams.
‘-XX:MinRAMPercentage’ JVM argument will be used to compute Java heap size only if your overall available memory’s size in the physical server (or in the container) is less than 250MB
The following table shows the values that are used when -XX:+UseContainerSupport is set:
Less than 1 GB 50% <size>
1 GB - 2 GB <size> - 512 MB
Greater than 2 GB 75% <size>
The default heap size is capped at 25 GB
The default heap size for containers takes affect only when the following conditions are met:
The application is running in a container environment.
The memory limit for the container is set.
The -XX:+UseContainerSupport option is set, which is the default behavior.
