Ok, after some code reading and asking around, I understand that LZ4 is not supported by COPY INTO. All supported formats (bz2, gz and xz) can be found in: https://www.monetdb.org/Documentation/Cookbooks/SQLrecipes/CSV_bulk_loads (section about COPY INTO "From compressed files”) Jennie

Dear all,

Is COPY INTO from an LZ4 file supported by MonetDB? When I try to load data from an LZ4 file, I always get the error:

Failed to import table 'pt', record too long (EOS found)

Is this an error or a missing feature?

Additional info: - MonetDB version Jul2017 (Mercurial source) - Mac OS (Sierra) - I checked the config.log that my lz4 lib was found - The LZ4 file is valid (I decompressed it, then I could load the data).

Thanks in advance!
