About HandlerSocket
HandlerSocket
is a NoSQL plugin
for MySQL. It works
as a daemon inside the
mysqld process, accept tcp connections,
and execute requests
from clients.
HandlerSocket does
not support
SQL queries. Instead, it supports simple CRUD
operations
on tables.
Because of the following reasons, HandlerSocket
is much faster than the
mysqld/libmysql pair
in some circumstances:
- HandlerSocket manipulates data without parsing
SQL, which causes less
CPU
usage.
- HandlerSocket
reads many requests
from clients
and executes their
requests
in bulk, which causes less CPU
and disk
usage.
- HandlerSocket client/server protocol
is more compact than the
mysql/libmysql pair, which causes less network
usage.
The current version of HandlerSocket only works
with GNU/Linux. The source
archive of HandlerSocket includes a C++
and a Perl client libraries.
