I'm just starting to learn about aerospike and thinking about the storage type for my application. Right now there is not too much data, so I'm plannning to use
storage-engine device with data-in-memory true.
However, should the size of the data increase in the future, would it be possible to change the settings to store only the indexes in RAM (remove data-in-memory true)? Would I need to do some kind of "database migration" or just comment out the line in config and restart the service?
Same question about filesize and memory-size parameters - if I increase these settings, should I somehow "resave" the data on disk?
For data-in-memory true, you can simply change to false and restart the asd daemon. Rolling restart will work (one node at a time), so no down time.
memory-size is actually dynamically configurable: see doc
filesize would require an asd daemon restart, one node at a time.
