#CREATE_KV_STORE test MemoryStore(createOnlyIfNotExists=false) /// default is true

Access a store

Currently, only MEP functions can be used to read an write from the store. So this can be used in all operators that contain expressions or predicates (e.g. Map operator or Select operator)

...

#PARSER PQL
#RUNQUERY
timer = TIMER({
            period = 1000,
            source = 'timersource'
          }
        )

Map1 = MAP({EXPRESSIONS = ['time','kvwrite("test2","Time",time)','kvread("test2", "Time")']}, timer)

You could also use an operator to write to an existing store:

StoreWriter

#PARSER PQL
#RUNQUERY
timer = TIMER({
            period = 1000,
            source = 'timersource'
          }
        )

out = StoreWriter({IdAttribute='time', store="test2")},timer)
