-----------------------------------------
Summary: sstableloader to stream sstables in a sorted order
Key: CASSANDRA-12416
URL: https://issues.apache.org/jira/browse/CASSANDRA-12416
Project: Cassandra
Issue Type: Wish
Reporter: Zhaojun Zhang
Within each sstable, the data is sorted. However, this is not true across
multiple sstables. We have a workflow which will create a read-only cluster by
bulk loading data from sstables (written by cqlsstablewirter) to cassandra
cluster. We don't want to trigger compaction, and the best way to do so is to
write data in a sorted order, which requires us to do a global sort across all
data sources using an external sort algorithm. If we are able to use
sstableloader to load data into clusters in order, we don't need to do such
global sort, which will dramatically simply our implementation and code
redundancy.
