Lindorm wide tables have various attributes, such as the number of retained column data versions, data compression method, data validity period, and the time period after which data is stored using cold storage. You can add attributes to or modify the attributes of existing tables in the cluster management system of LindormTable.
Procedure
Log on to the cluster management system of Lindorm.
In the navigation pane on the left, choose .
Select the attribute that you want to change from the Alter Type drop-down list. The following table describes the attributes that you can modify for a table.
Table attribute
Description
Consistency

strong: Data in the base table and index table are consistent at all points in time.
Mutability
An option related to indexes. This option specifies the mutability of the base table.
Valid values:
IMMUTABLE
IMMUTABLE_ROWS
MUTABLE_LATEST
MUTABLE_ALL
For more information, see Secondary indexes.
Enable dynamic columns

modify TTL
The TTL for data, in seconds (s). To retain data permanently, set the value to
-1.modify compression type
The algorithm used to compress data in the table. Default value: NONE. The following algorithms are supported: SNAPPY, ZSTD, and LZ4.
