td table:partial_delete command lets you delete your imported data within a specific table by specifying the time range.
We generally recommend using the more flexible Presto DELETE query statement instead of partial-delete.
- Basic knowledge of Treasure Data, including the TD toolbelt.
- The partial_delete procedure can only delete data from Archive storage and won't alter Realtime storage data.
Data imported Is stored at least 1 hour before or earlier than when you want to delete it in columnar compressed format and partitioned by hour in Archive storage 1 hour before or less in a raw msgpack compressed format and is not partitioned by hour in Realtime storage
Partial Delete Syntax
Because the stored data is partitioned by hour, the arguments for
--to must be an integer multiple of 3600 (1 hour).
td table:partial_delete <db> <table>
$ TD table:partial_delete example_db table1 --from 1341000000 --to 1341003600
The data deletion is executed as a
job. This means that you can confirm its status by issuing the
td jobs command (see Job Management). The
-w option allows you to wait until the job is finished.
