-- Restores the specified table to the specified point in time within @EarliestRestorableDateTime@ and @LatestRestorableDateTime@ . You can restore your table to any point in time during the last 35 days. Any number of users can execute up to 4 concurrent restores (any type of restore) in a given account.
--
--
-- When you restore using point in time recovery, DynamoDB restores your table data to the state based on the selected date and time (day:hour:minute:second) to a new table.
--
-- Along with data, the following are also included on the new restored table using point in time recovery:
--
--     * Global secondary indexes (GSIs)
--
--     * Local secondary indexes (LSIs)
--
--     * Provisioned read and write capacity
--
--     * Encryption settings
--
-- /Important:/ All these settings come from the current settings of the source table at the time of restore.
--
--
--
-- You must manually set up the following on the restored table:
--
--     * Auto scaling policies
--
--     * IAM policies
--
--     * Cloudwatch metrics and alarms
--
--     * Tags
--
--     * Stream settings
--
--     * Time to Live (TTL) settings
--
--     * Point in time recovery settings
