This causes their performance - and by extension - that of your database queries, to degrade.
Hence, rebuilding indexes every now and again can be quite beneficial..

Can I use archival compression on a clustered ColumnStore index?

We recommend only using this on data that isn't accessed often since decompress is slower than with the normal COLUMNSTORE compression.
The following example rebuilds a clustered columnstore index to use archival compression, and then shows how to remove the archival compression.
The final result will use only columnstore compression.

How do I enable data compression when creating a table or index?

To enable data compression when creating a table or index, see the Create a compressed index and Creating a table that uses row compression examples.
System tables can't be enabled for compression.
If the table is a heap, the rebuild operation for ONLINE mode is single threaded.
Use OFFLINE mode for a multi-threaded heap rebuild operation.

How do I remove archival compression in SQL Server?

To remove archival compression and restore the data to columnstore compression, use ALTER TABLE (Transact-SQL) or ALTER INDEX (Transact-SQL) with the REBUILD option and DATA COMPRESSION = COLUMNSTORE.
This next example sets the data compression to columnstore on some partitions, and to columnstore archival on other partitions.
