COPY from S3 to Redshift with manifest fails

0

Hi,

I need to load data from Aurora (MySQL) to Redshift and using S3 is one of the available options. I can extract data from Aurora (MySQL) to S3 using:

SELECT *
FROM data_table
INTO OUTFILE S3 's3-XXX://bucket_name/aurora_files/data_table'
    FORMAT CSV HEADER
    FIELDS TERMINATED BY ';'
    LINES TERMINATED BY '\n'
    OVERWRITE ON;

and load the same data to Redshift using:

copy data_table
from 's3://bucket_name/aurora_files/data_table.part_00000'
access_key_id 'XXX'
secret_access_key 'XXX'
csv
delimiter ';'
ignoreheader 1
timeformat 'YYYY-MM-DD HH:MI:SS'
region 'XXX';

If I try to extract data with Manifest and load that from Manifest, I get the following error:

[2022-03-14 18:08:52] [XX000] ERROR: S3 path "s3-XXX://bucket_name/aurora_files/data_table.part_00000" has invalid format.

Following commands are used to create S3 file and load that to Redshift with manifest:

SELECT *
FROM data_table
INTO OUTFILE S3 's3-XXX://bucket_name/aurora_files/data_table'
    FORMAT CSV HEADER
    FIELDS TERMINATED BY ';'
    LINES TERMINATED BY '\n'
    MANIFEST ON
    OVERWRITE ON;
copy data_table
from 's3://bucket_name/aurora_files/data_table.manifest'
access_key_id 'XXX'
secret_access_key 'XXX'
csv
delimiter ';'
ignoreheader 1
timeformat 'YYYY-MM-DD HH:MI:SS'
region 'XXX'
manifest;

What could be the issue?

Is the file 's3://bucket_name/aurora_files/data_table.part_00000' manifest file? You should point out manifest file or only prefix such as 's3://bucket_name/aurora_files/data_table'
