The loader can be used to load into global and central tables via the following command:
joloader <network> <file> <table> [switches] -E~"select copy_rows('%t');"
<network> is the name of the network or database to load the data into
<file> is the name of the file to load from
<table> is the name of a table to load into
[switches] is zero, one or more switches which control file parsing and data interpretation
By default (without any switches), the loader will assume the source file is in CSV format with the same fields in the same order as the columns in the destination table.
