You can write data to the local /tmp disk. Just be aware that:

• There is no guarantee that the data will be there next time, as instances are spun up and down as needed. So you will need to check if the file exists on each call, and be ready to create it when it doesn't exist yet.
• The /tmp disk space is a RAM disk, so any files written there will come out of the memory you've allocated for your Cloud Functions containers.
• You can't reliably keep listeners alive across calls, so you won't be able to update the cache.
