    You can use Tablestore SDK for Java to manage the TimeSeries model based on the following general procedure:

    1. Initialize a client to access your Tablestore instance. For more information, see Initialization.

    2. Create time series tables to store data. For more information, see Create a time series table.

    3. Read data from or write data to the time series tables. For more information, see Write time series data and Query time series data.

    4. Retrieve time series. For more information, see Retrieve time series.

    5. Execute SQL statements to query data. For more information, see SQL query.
