Transactd
Transactd manipulates internal database access method to MySQL/MariaDB directly, and provides the flexible high-speed database access.
In general, NoSQL has some limitations such as can not use the transaction. But Transactd will can use transaction in the same way as SQL.
Operation with SQL is that: parse SQL syntax in the server, decompose to row basis access methods, processing, and returns the result.
Transactd make it possible to control these row basis processing in the client side. And the API is very simple.
For example, following code shows how to print id and name of all records in
users table.
db = Transactd::Database.new()
db.open('tdap://servername/dbname?dbfile=transactd_schema')
tb = db.openTable('users', Transactd::TD_OPEN_NORMAL)
tb.seekFirst()
while (tb.stat() == 0) do
puts('id = ' + tb.getFVint('id').to_s() + ', name = ' + tb.getFVstr('name'))
tb.seekNext()
end
tb.close()
db.close()There are more APIs. See tutorial to overview main features of Transactd.
