=head1 NAME
 
    Bio::EnsEMBL::Hive::Examples::LongMult::PipeConfig::LongMultWfServer_conf;
 
=head1 SYNOPSIS
 
       # initialize the "server" database first and note its URL - you will need it to initialize the "client" later:
    init_pipeline.pl Bio::EnsEMBL::Hive::Examples::LongMult::PipeConfig::LongMultWfServer_conf -password <mypass>
 
       # initialize the "client" database by plugging the server's URL:
    init_pipeline.pl Bio::EnsEMBL::Hive::Examples::LongMult::PipeConfig::LongMultWfClient_conf -password <mypass> -server_url $SERVER_HIVE_URL
 
        # optionally also seed it with your specific values:
    seed_pipeline.pl -url $CLIENT_HIVE_URL -logic_name take_b_apart -input_id '{ "a_multiplier" => "12345678", "b_multiplier" => "3359559666" }'
 
        # run the "server" (it will have to be stopped manually when the "client" is done):
    beekeeper.pl -url $SERVER_HIVE_URL -keep_alive
 
        # run the "client" (it will exit by itself):
    beekeeper.pl -url $CLIENT_HIVE_URL -loop
 
=head1 DESCRIPTION
 
    This is the "server" PipeConfig file of a special two-part version of the long multiplication example pipeline.
    Please make sure you FULLY understand how the LongMult_conf works before trying this one.
 
    We have split the original LongMult_conf into two parts, the "client" and the "server" that can be used to initialize
    two separate Hive pipeline databases.
 
    The "client" kept 'take_apart' and 'add_together' analyses and the 'final_result' table, but the 'part_multpily' analysis
    has been outsourced into the "server" which also maintains its local 'intermediate_result' table.
 
    There are 3 links between the pipelines, all established from the "client" side (the "server" doesn't know about them) :
        1. The "client" seeds the "server" via a cross-database dataflow rule ('take_b_apart'#2 -> 'part_multiply)
        2. The "client" waits for the 'part_multiply' analysis to complete on the "server" via an analysis_ctrl_rule
        3. The "client" reads the data from the 'intermediate_result' table of the "server"
