取决于数据库的设置,设置为滚动保存时,会覆盖最早的,否则就提示插入失败了,需要用户手动清空数据库

详见 control API https://github.com/armink/FlashDB/blob/master/src/fdb_tsdb.c#L671

请问,fdb_tsl_query_count(fdb_tsdb_t db, fdb_time_t from, fdb_time_t to, fdb_tsl_status_t status),这个函数中,fdb_tsl_status_t status主要做什么作用?

我看说明上修改状态:
NOTE: The actions to modify the state must be in order.
* FDB_TSL_WRITE -> FDB_TSL_USER_STATUS1 -> FDB_TSL_DELETED -> FDB_TSL_USER_STATUS2
这些状态位,必须顺序修改吗?

TSDB 启用滚动写入,当可用扇区写满的时候,是不是最早的一整个扇区的数据都会被清除,而不是一条一条清除?
