Use the Tablestore SDK for Go to update the TTL of a search index or adjust traffic and switch indexes during dynamic schema modification.
Prerequisites
Install the Tablestore Go SDK and initialize a client.
Description
Call UpdateSearchIndex to update the TTL of a search index. During dynamic schema modification, you can also use this method to set query traffic weights for the source and reindex indexes or switch the two indexes. For the complete workflow, see Dynamically modify a search index schema.
func (client *tablestore.TableStoreClient) UpdateSearchIndex(request *tablestore.UpdateSearchIndexRequest) (*tablestore.UpdateSearchIndexResponse, error)ttl := int32(7 * 24 * 60 * 60)
_, err := client.UpdateSearchIndex(&tablestore.UpdateSearchIndexRequest{
TableName: "example_table",
IndexName: "example_index",
TimeToLive: &ttl,
})
if err != nil {
log.Fatal(err)

TimeToLive (optional) |
*int32 |
The TTL of index data in seconds. Valid values are -1 and int32 integers no less than 86,400. -1 indicates that data never expires. For a non--1 value, UpdateRow updates must be disabled, and the index TTL cannot exceed the table TTL. For more information, see Configure the TTL of a search index. |

QueryFlowWeights (optional) |
[]*tablestore.QueryFlowWeight |
The query traffic weights for the source and reindex indexes. The Weight values must add up to 100. |
|
SwitchIndexName (optional) |
*string |
The reindex index whose target is switched with IndexName. |
