Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

STV_LOAD_STATE

Use the STV_LOAD_STATE table to find information about current state of ongoing COPY statements.

The COPY command updates this table after every million records are loaded.

STV_LOAD_STATE is visible to all users. Superusers can see all rows; regular users can see only their own data. For more information, see Visibility of data in system tables and views.

Table columns

Column name Data type Description
userid integer ID of user who generated entry.
session integer Session PID of process doing the load.
query integer Query ID. Can be used to join various other system tables and views.
slice integer Node slice number.
pid integer Process ID. All of the queries in a session are run in the same process, so this value remains constant if you run a series of queries in the same session.
recordtime timestamp Time the record is logged.
bytes_to_load bigint Total number of bytes to be loaded by this slice. This is 0 if the data being loaded is compressed
bytes_loaded bigint Number of bytes loaded by this slice. If the data being loaded is compressed, this is the number of bytes loaded after the data is uncompressed.
bytes_to_load_compressed bigint Total number of bytes of compressed data to be loaded by this slice. This is 0 if the data being loaded is not compressed.
bytes_loaded_compressed bigint Number of bytes of compressed data loaded by this slice. This is 0 if the data being loaded is not compressed.
lines integer Number of lines loaded by this slice.
num_files integer Number of files to be loaded by this slice.
num_files_complete integer Number of files loaded by this slice.
current_file character(256) Name of the file being loaded by this slice.
pct_complete integer Percentage of data load completed by this slice.

Sample query

To view the progress of each slice for a COPY command, type the following query. This example uses the PG_LAST_COPY_ID() function to retrieve information for the last COPY command.

select slice , bytes_loaded, bytes_to_load , pct_complete from stv_load_state where query = pg_last_copy_id();

 slice | bytes_loaded | bytes_to_load | pct_complete 
-------+--------------+---------------+--------------
     2 |            0 |             0 |            0
     3 |     12840898 |      39104640 |           32
