Tokyo Cabinet 1.3.9 (Default branch)
Tokyo Cabinet is a library of routines for managing a database. It is the successor of QDBM. Tokyo Cabinet runs very fast. For example, the time required to store 1 million records is 1.5 seconds for a hash database and 2.2 seconds for a B+ tree database. Moreover, the database size is very small. For example, the overhead for a record is 16 bytes for a hash database, and 5 bytes for a B+ tree database. Furthermore, the scalability of Tokyo Cabinet is great. The database size can be up to 8EB.

The database server now supports the Lua extension, which enables this release to add arbitrary database operations defined by users. A bug related to replication was fixed. Image

NAME

       tcftest - test cases of the fixed-length database API

DESCRIPTION

       The command `tcftest' is a utility for facility test and performance test.  This command is used in the following format.  `path' specifies
       the path of a database file.  `rnum' specifies the number of iterations.  `width' specifies the width of the value of each  record.   `lim-
       siz' specifies the limit size of the database file.

	      tcftest write [-mt] [-nl|-nb] [-rnd] path rnum [width [limsiz]]
		     Store records with keys of 8 bytes.  They change as `00000001', `00000002'...
	      tcftest read [-mt] [-nl|-nb] [-wb] [-rnd] path
		     Retrieve all records of the database above.
	      tcftest remove [-mt] [-nl|-nb] [-rnd] path
		     Remove all records of the database above.
	      tcftest rcat [-mt] [-nl|-nb] [-pn num] [-dai|-dad|-rl] path rnum [limsiz]]
		     Store records with partway duplicated keys using concatenate mode.
	      tcftest misc [-mt] [-nl|-nb] path rnum
		     Perform miscellaneous test of various operations.
	      tcftest wicked [-mt] [-nl|-nb] path rnum
		     Perform updating operations selected at random.

       Options feature the following.

	      -mt : call the function `tcfdbsetmutex'.
	      -nl : enable the option `FDBNOLCK'.
	      -nb : enable the option `FDBLCKNB'.
	      -rnd : select keys at random.
	      -wb : use the function `tcfdbget4' instead of `tcfdbget2'.
	      -pn num : specify the number of patterns.
	      -dai : use the function `tcfdbaddint' instead of `tcfdbputcat'.
	      -dad : use the function `tcfdbadddouble' instead of `tcfdbputcat'.
	      -rl : set the length of values at random.

       This command returns 0 on success, another on failure.
