-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi, MonetDB 'deduplicates' strings, is there any benchmark that outlines the performance difference of an ENUM with a low number of (string)items versus the use of a VARCHAR field? The technical question would be; Is it more efficient to do: select * from my_table, my_enum where mytable.my_enum_id = my_enum.id and my_enum.name = 'Something'; or select * from my_table where my_enum_varchar = 'something'; I can imagine that the following would out perform a string comparison, but implies hardcoded values. select * from my_table, my_enum where mytable.my_enum_id = hardcoded; Stefan -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEAREKAAYFAk78fnkACgkQYH1+F2Rqwn3BUQCeOUtPIGzcHT1xpnsF4n78BQ/1 JWAAnjnzPeT8D7CtsjYgAiGg/WRIgNbQ =989f -----END PGP SIGNATURE-----
