Docker QuestDB 'Java Heap Space' Error: Cause and Solution

'Java heap space' errors occur when Java applications exceed their allocated memory limit. To resolve this issue in Docker QuestDB, you can increase the maximum heap size by setting the '-Xmx' JVM parameter. For example, to allocate 4GB of heap space, use the following command:

java -Xmx4G -jar questdb.jar

This adjustment will provide your QuestDB application with the necessary memory to operate without encountering 'Java heap space' errors.
