# I'm thinking we store a couple things
# first: a key-value where the value is the dictlist
# second: a k-v for a list of errored events

# use rpush(key, value) to append a dblist (rpushx() to check if it exists)
# use del(key) to remove a k-v

# so everytime we run parscript or gcscript we want to run a dbfill()
# function. and every time we find an error we want to run a dberrorfill()
# function.
