SQLObject is an object-relational mapper.
It allows you to translate RDBMS table rows into Python objects,
and manipulate those objects to transparently manipulate the database.
Swift is a highly available, distributed, eventually consistent
object/blob store.
MemcacheQ is a Simple Queue Service over Memcache.
Features:
* damn simple
* very fast
* multiple queue
* concurrent well
* memcache protocol compatible
QDBM is a library of routines for managing a database. The database
is a simple data file containing records, each is a pair of a key and
a value. Every key and value is serial bytes with variable length.
Both binary data and character string can be used as a key and a
value. There is neither concept of data tables nor data types.
Records are organized in hash table or B+ tree.
Riak is an open source, distributed database. Riak is architected for:
* Low-Latency
Riak is designed to store data and serve requests predictably and quickly, even
during peak times.
* Availability
Riak replicates and retrieves data intelligently, making it available for read
and write operations even in failure conditions.
* Fault-Tolerance
Riak is fault-tolerant so you can lose access to nodes due to network partition
or hardware failure and never lose data.
* Operational Simplicity
Riak allows you to add machines to the cluster easily, without a large
operational burden.
It is pretty easy to gather status information from all sorts of things,
ranging from the temperature in your office to the number of octets which
have passed through the FDDI interface of your router. But it is not so
trivial to store this data in a efficient and systematic manner. This is
where RRDtool kicks in. It lets you log and analyze the data you gather from
all kinds of data-sources. The data analysis part of RRDtool is based
on the ability to quickly generate graphical representations of the data
values collected over a definable time period.
tokyocabinet-ruby provides an interface to the Toky Cabinet database
engine.
A toolkit for building modeling frameworks like Active Record and
Active Resource. Rich support for attributes, callbacks,
validations, observers, serialization, internationalization,
and testing.
