Lindorm wide tables support various table attributes, such as the number of versions to retain for column values, data compression methods, time-to-live (TTL), and cold storage thresholds. You can add or modify table attributes for existing wide tables in the cluster management system.
Procedure
In the left navigation pane, choose .
From the Alter type drop-down list, select the table attribute to modify. The following table describes the available table attributes:
Parameter
Description
Consistency
The consistency level of the table. By default, the base table and index tables are eventually consistent. The following levels are supported:
eventual: The default value. The base table and index tables become consistent over time.
strong: The data in the base table and index tables are synchronized and consistent at all times.
Mutability
An index-related attribute that specifies the write pattern for the base table.
Supported values:
IMMUTABLE
IMMUTABLE_ROWS
MUTABLE_LATEST
MUTABLE_ALL
For more information, see secondary index.
Enable dynamic columns
Enables the dynamic column feature for the table. For more information, see dynamic column.
Modify version
The number of versions to retain for column values. The value must be an integer of 1 or greater. The default is 1.
Compaction Period
The interval for a
major compaction, in milliseconds (ms). The minimum value is 3,600,000, which is equivalent to 1 hour.Modify TTL
The time-to-live (TTL) for data, in seconds (s). To retain data permanently, enter
-1.Modify compression type
The data compression algorithm. By default, no compression is used (NONE). Supported algorithms include SNAPPY, ZSTD, and LZ4.
Modify cold storage threshold
The cold storage threshold, in seconds (s). The minimum value is 1.
NoteFor more information about table attributes, see Table attributes (table_options).
Select the Namespace and the wide table that you want to modify.
Set the attribute value, and then click Submit.
