 - Can do quick binary search on RowID or Timestamp without any index in logarithmic time
 - Recovery possible in case of power failure
 - Rolling logs are possible (not implemented yet)

 The examples `ESP8266_Console` and `ESP32_Console` can be used to log and retrieve from ESP8266 and ESP32 boards respectively on Micro SD and SPIFFS filesystems.

 If there is power failure during logging, the data can be recovered using `Recover database` option in the menu.

 - `Select`, `Insert` are not supported.  Instead C API similar to that of Sqlite API is available.

+However, the database created can be copied to a desktop PC and further operations such as index creation and summarization can be carried out from there as though its a regular Sqlite database.  But after doing so, it may not be possible to use it with this library any longer.

+# Future plans
+
+- Index creation when finalizing a database
+- Allow modification of records
+- Rolling logs
+- Show how this library can be used in a multi-core, multi-threaded environment
