SHMLOAD Extension: io.warp10.script.ext.shm.SharedMemoryWarpScriptExtension
SHMLOAD function loads data previously stored by
SHMSTORE in shared memory, i.e. in a memory location independent of a given execution context.
The call will fail if the requested shared symbol is not known or if the calling script does not currently hold the mutex associated with the symbol.
shm.ttl configuration, in millisecond, allow you to tune the retention time in memory. Default value is one hour. Tip: you can call
SHMLOAD in a runner with a period shorter than
shm.ttl if you want to keep value in memory indefinitely.
