NAME
K - Perl bindings for k (aka q, aka kdb, aka kx)
SYNOPSIS
my $k = K->new(
host => 'kserver.example.com',
port => 5000,
user => 'awhitney',
password => 'kdb4eva',
);
$k->cmd( '4 + 4' ); # 8
$k->cmd( q/"abc"/ ); # [ 'a', 'b', 'c' ]
$k->cmd( q/`foo`bar!(1;2)/ ); # { foo => 1, bar => 2 }
$k->cmd( q/2012.03.24D12:13:14.15161728/ ); # '385906394151617280'
# table
$k->cmd( q/([] foo: (`a;`b); bar: (`c;`d))/ );
# {
# foo => ['a', 'b'],
# bar => ['c', 'd'],
# }
# table w/ primary key
$k->cmd( q/([p: (`a;`b)] foo: (`b;`c); bar: (`d;`e))/ );
# [
# {
# p => ['a', 'b']
# }
# {
# foo => ['b', 'c'],
# bar => ['d', 'e'],
# },
# ]DESCRIPTION
Connect to a remote K or Q instance. Execute commands. Read replies.
K wraps the C library defined by k.h and described here http://code.kx.com/wiki/Cookbook/InterfacingWithC .
K's OO interface is a thin layer of sugar on top of K::Raw which mimics the C library as faithfully as possible.
For now, K returns very simple Perl representations of k values. For example, inside k timestamps are 64-bit ints where the value is the number of nanoseconds since 2001.01.01D00:00:00.000 . For such values, K returns the int value as a string (ex: '385906394151617280'). This will probably change.
