Update the configurations of a search index
Updates the time to live (TTL) of a search index using Tablestore SDK for Node.js by calling the UpdateSearchIndex operation.
Prerequisites
An OTSClient instance is initialized. For more information, see Initialize an OTSClient instance.
A search index exists for the data table.
The
allowUpdateparameter is set tofalsefor the data table. For more information, see Update the configurations of a table.
Usage notes
-
The TTL of a search index is independent of and must be no greater than that of the data table for which the search index is created. If you want to decrease the TTL of a search index and the data table for which the search index is created, you must change the TTL of the search index before you change the TTL of the data table.
-
Tablestore automatically deletes expired data from search indexes every day. You can still query expired data in search indexes before the expired data is deleted. Tablestore automatically deletes the expired data in the next cycle.
-
After you change the TTL of data tables and search indexes, Tablestore automatically deletes the historical expired data from the data tables and search indexes in the next cycle.

Description |
|
tableName (required) |
The name of the data table. |
|
indexName (required) |
The name of the search index. |
|
timeToLive (required) |
The TTL of the search index, in seconds. Set to |
Examples
The following example sets the TTL of a search index to seven days (604,800 seconds):
let params = {
tableName: '<TABLE_NAME>',
indexName: '<SEARCH_INDEX_NAME>',
timeToLive: 604800, // 7 days in seconds (7 x 24 x 60 x 60)
}
client.updateSearchIndex(params, function (err, data) {
if (err) {
console.log('updateSearchIndex error:', err.toString());
} else {
console.log('updateSearchIndex success:', data);
}
});
To calculate the timeToLive value for a different duration, multiply the number of days by 86400 (seconds per day). For example, 30 days is 2592000.
