| 5 summary: Experimental map store optimized for small incremental changes | |
| 6 ... | |
| 7 | |
| 8 This is an experimental storage driver where changed data is appended. | |
| 9 Data is simply written as `key = value` pairs to the end of the file. | |
| 10 This allows changes to individual keys to be written without needing to | |
| 11 write out the entire object again, but reads would grow gradually larger | |
| 12 as it still needs to read old overwritten keys. This may be suitable for | |
| 13 eg rosters where individual contacts are changed at a time. In theory, | |
| 14 this could also allow rolling back changes. | |
