LMT: Switch the hot partition data that is not updated in the last [day] days to the OBS tablespace as cold partition data. [day] is an integer ranging from 0 to 36500, in days.
OBS GaussDB(DWS) uses OBS to convert cluster data and external data, satisfying the requirements for secure, reliable, and cost-effective storage. MRS Data can be migrated from MRS to GaussDB(DWS) clusters for analysis after the data is processed by Hadoop.
The foreign server associated with the table is hdfs_server, the format of the file on HDFS corresponding to the table is ORC, and the data storage path on OBS is /user/hive/warehouse/product_info_orc/.
Servers whose type is lf, dli, obs, or hdfs can be associated. For details, see CREATE SERVER. CATALOG Catalog to be accessed in LakeFormation.

OBS Path: Find the product_info.txt file in the created OBS bucket and click Yes. HDFS Path: Select /user/hive/warehouse/demo.db/product_info/ and click Yes. Click OK to import the product_info table data. Create an ORC table and import data to the table.
OBS I/O indicates details about an OBS I/O request. (supported by V3 tables or foreign tables with storage and compute decoupled) count indicates the total number of OBS I/O requests. averageRTT indicates the average round trip time (RTT) of OBS I/O requests.

Analyzing a Table ANALYZE supports row-store, column-store, HDFS, and OBS tables in ORC or CARBONDATA format. ANALYZE can also collect statistics about specified columns of a local table.
Full export: Export all query SQL results to a specified path in an OBS bucket. By default, the results are exported to a CSV file. For details, see Exporting Data. Using gs_dump and gs_dumpall Alternatively, you can use gs_dump and gs_dumpall to export data.
However, if you use more space than the free-of-charge storage space, the exceeded part is charged according to OBS billing rules. For details, see the OBS pricing details.
Currently, you can only use the snapshots stored in OBS to restore data to a new cluster. The resources required for restoring data to a new cluster do not exceed your available resource quota.
Check whether OBS is running properly. If it is, contact technical support to check whether the dms-agent process is normal. DWS.13009 The OBS storage space is insufficient. Ensure the OBS storage space is sufficient. DWS.0107 DN REDO is being executed. Try again later.

Transferring Data to OBS Raw data of metrics is kept for two days on Cloud Eye. You can enable OBS and save the raw data to OBS so that it can be saved for a longer time.
CREATE DATABASE OBS foreign tables support XSKY S3. OBS foreign tables are adapted to XSKY and the parameter eol is added. CREATE FOREIGN TABLE (SQL on Hadoop or OBS) SQL supports Roaring Bitmaps.
However, if you use more space than the free-of-charge storage space, the exceeded part is charged according to OBS billing rules. For details, see the OBS pricing details.
This section describes how to import sample data from OBS to a data warehouse cluster and perform querying and analysis operations on the sample data. The sample data is generated based on the standard TPC-DS benchmark test.
