@ -92,8 +92,8 @@ SeaweedFS Cloud Drive has these unique characteristics:
* Accessing cloud data is slow and costly.
* Recently uploaded files very likely need to be accessed again.
* With SeaweedFS Cloud Drive
* Users can explicitly ask SeaweedFS Cloud Drive to uncache by file age.
* Users can also choose to never uncache, basically treating cloud copy as a backup.
* The local copy and remote copy can be backup for each other, if users choose not to uncache.
* To keep recent data in local copy, users can choose to only uncache files older than a limit.
## Big Data
* Problem
* Run MapReduce, Spark, and Flink jobs on cloud data is slow due to metadata operations.
