A table is loaded using Snowpipe and truncated afterwards. Later, a Data Engineer finds that the table needs to be reloaded, but the metadata of the pipe will not allow the same files to be loaded again.
How can this issue be solved using the LEAST amount of operational overhead?
When reloading files using Snowpipe, the FORCE=TRUE option is not valid for Snowpipe operations. To resolve the issue of reloading the table with the least amount of operational overhead, recreating the pipe with the CREATE OR REPLACE PIPE command is the most efficient approach. This allows the same files to be loaded again without altering the contents of the files or waiting for the metadata to expire. This operation ensures that the pipeline is reset and ready to process the files once more.
Snowpipe ignores modified files that are staged again. To reload modified data files, it is currently necessary to recreate the pipe object using the CREATE OR REPLACE PIPE syntax. https://docs.snowflake.com/en/user-guide/data-load-snowpipe-ts
Files modified and staged again within 14 days : Snowpipe ignores modified files that are staged again. To reload modified data files, it is currently necessary to recreate the pipe object using the CREATE OR REPLACE PIPE syntax.
https://docs.snowflake.com/en/sql-reference/sql/create-pipe#usage-notes FORCE is not a valid option for Snowpipe: -----All COPY INTO <table> copy options are supported except for the following: FILES = ( 'file_name1' [ , 'file_name2', ... ] ) ON_ERROR = ABORT_STATEMENT SIZE_LIMIT = num PURGE = TRUE | FALSE (i.e. automatic purging while loading) FORCE = TRUE | FALSE RETURN_FAILED_ONLY = TRUE | FALSE VALIDATION_MODE = RETURN_n_ROWS | RETURN_ERRORS | RETURN_ALL_ERRORS
I think is D. If you modify the COPY INTO statement you need to recreate the pipe. Then you need to (1) modify the COPY INTO and (2)recreate the pipe. 2 Steps. If you recreate the pipe directly you will reload again the files. 1 Step.
C. Set the FORCE=TRUE option in the Snowpipe COPY INTO command. Using the FORCE=TRUE option in the Snowpipe COPY INTO command allows reloading files even if they have been loaded previously. This can be useful in situations where you need to reload data, and the metadata of the pipe is preventing the same files from being loaded again. It minimizes operational overhead by avoiding the need to wait for metadata expiration or modifying the files.
According to https://docs.snowflake.com/en/sql-reference/sql/copy-into-table FORCE = TRUE would "load all files, regardless of whether they’ve been loaded previously and have not changed since they were loaded". The question asked for the least impact. C is the least impact
