Delete time series

Prerequisites

A client is initialized. For more information, see Initialize a Tablestore client.

Parameters

Time series identifiers are used to identify a time series. You can specify time series identifiers of multiple time series to delete the metadata of multiple time series. The following table describes the parameters.

Example

The following sample code provides an example on how to delete the metadata of multiple time series in a time series table:

private static void deleteTimeseriesMeta(TimeseriesClient client) {
    List<TimeseriesKey> timeseriesKeyList = new ArrayList<TimeseriesKey>();
    for (int i = 0; i < 10; i++) {
        Map<String, String> tags = new HashMap<String, String>();
        tags.put("region", "hangzhou");
        tags.put("os", "Ubuntu16.04");
        // Construct time series identifier.
        TimeseriesKey timeseriesKey = new TimeseriesKey("cpu", "host_" + i, tags);
        timeseriesKeyList.add(timeseriesKey);
    }
    // Specify the name of the time series table.
    String tableName = "<TIME_SERIES_TABLE>";
    DeleteTimeseriesMetaRequest deleteTimeseriesMetaRequest = new DeleteTimeseriesMetaRequest(tableName);
    deleteTimeseriesMetaRequest.setTimeseriesKeys(timeseriesKeyList);
    DeleteTimeseriesMetaResponse deleteTimeseriesMetaResponse = client.deleteTimeseriesMeta(deleteTimeseriesMetaRequest);
    // Check whether the metadata of the time series is deleted.
    if (!deleteTimeseriesMetaResponse.isAllSuccess()) {
        for (DeleteTimeseriesMetaResponse.FailedRowResult failedRowResult : deleteTimeseriesMetaResponse.getFailedRows()) {
            System.out.println(failedRowResult.getIndex());
            System.out.println(failedRowResult.getError());
        }
    }
}
