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
tcfmttest - test cases of the fixed-length database API DESCRIPTION
The command `tcfmttest' is a utility for facility test under multi-thread situation. This command is used in the following format. `path' specifies the path of a database file. `tnum' specifies the number of running threads. `rnum' specifies the number of iterations. `width' specifies the width of the value of each record. `limsiz' specifies the limit size of the database file. tcfmttest write [-nl|-nb] [-rnd] path tnum rnum [width [limsiz]] Store records with keys of 8 bytes. They change as `00000001', `00000002'... tcfmttest read [-nl|-nb] [-wb] [-rnd] path tnum Retrieve all records of the database above. tcfmttest remove [-nl|-nb] [-rnd] path tnum Remove all records of the database above. tcfmttest wicked [-nl|-nb] [-nc] path tnum rnum Perform updating operations selected at random. tcfmttest typical [-nl|-nb] [-nc] [-rr num] path tnum rnum [width [limsiz]] Perform typical operations selected at random. Options feature the following. -nl : enable the option `FDBNOLCK'. -nb : enable the option `FDBLCKNB'. -rnd : select keys at random. -wb : use the function `tcfdbget4' instead of `tcfdbget2'. -nc : omit the comparison test. -rr num : specifiy the ratio of reading operation by percentage. This command returns 0 on success, another on failure. SEE ALSO
