promkv is a joke key-value store backed by Prometheus.
Key-value pairs are stored as three different time series:
promkv_file_timestamp_seconds: The timestamp where the most recent write of the key-value pair starts.promkv_file_size_bytes: The size of the most recent write, in bytes.promkv_file_content: The content of the most recent write. Each byte of the value is uploaded as a different sample one second apart.
The name of the key is stored as the key label.
Do not use this in production; promkv is almost guaranteed to do something
wrong and will probably lose data.
