Tokyo Cabinet 1.3.12 (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.

A script binding interface for Lua was added. Some utility functions were added to the network server. Concurrency of the hash database was improved. Image

NAME

       tcbmgr - the command line utility of the B+ tree database API

DESCRIPTION

       The  command `tcbmgr' is a utility for test and debugging of the B+ tree database API and its applications.  `path' specifies the path of a
       database file.  `lmemb' specifies the number of members in each leaf page.  `nmemb' specifies the number of members in each non-leaf  page.
       `bnum'  specifies  the number of buckets.  `apow' specifies the power of the alignment.	`fpow' specifies the power of the free block pool.
       `key' specifies the key of a record.  `value' specifies the value of a record.  `file' specifies the input file.

	      tcbmgr create [-cd|-ci|-cj] [-tl] [-td|-tb|-tt|-tx] path [lmemb [nmemb [bnum [apow [fpow]]]]]
		     Create a database file.
	      tcbmgr inform [-nl|-nb] path
		     Print miscellaneous information to the standard output.
	      tcbmgr put [-cd|-ci|-cj] [-nl|-nb] [-sx] [-dk|-dc|-dd|-db|-dai|-dad] path key value
		     Store a record.
	      tcbmgr out [-cd|-ci|-cj] [-nl|-nb] [-sx] path key
		     Remove a record.
	      tcbmgr get [-cd|-ci|-cj] [-nl|-nb] [-sx] [-px] [-pz] path key
		     Print the value of a record.
	      tcbmgr list [-cd|-ci|-cj] [-nl|-nb] [-m num] [-bk] [-pv] [-px] [-j str] [-rb bkey ekey] [-fm str] path
		     Print keys of all records, separated by line feeds.
	      tcbmgr optimize [-cd|-ci|-cj] [-tl] [-td|-tb|-tt|-tx] [-tz] [-nl|-nb] [-df] path [lmemb [nmemb [bnum [apow [fpow]]]]]
		     Optimize a database file.
	      tcbmgr importtsv [-nl|-nb] [-sc] path [file]
		     Store records of TSV in each line of a file.
	      tcbmgr version
		     Print the version information of Tokyo Cabinet.

       Options feature the following.

	      -cd : use the comparison function `tccmpdecimal'.
	      -ci : use the comparison function  `tccmpint32'.

	      -tx : enable the option `BDBTEXCODEC'.
	      -nl : enable the option `BDBNOLCK'.
	      -nb : enable the option `BDBLCKNB'.
	      -sx : the input data is evaluated as a hexadecimal data string.
	      -dk : use the function `tcbdbputkeep' instead of `tcbdbput'.
	      -dc : use the function `tcbdbputcat' instead of `tcbdbput'.
	      -dd : use the function `tcbdbputdup' instead of `tcbdbput'.
	      -db : use the function `tcbdbputdupback' instead of `tcbdbput'.
	      -dai : use the function `tcbdbaddint' instead of `tcbdbput'.
	      -dad : use the function `tcbdbadddouble' instead of `tcbdbput'.
	      -px : the output data is converted into a hexadecimal data string.
	      -pz : do not append line feed at the end of the output.
	      -m num : specify the maximum number of the output.
	      -bk : perform backword scanning.
	      -pv : print values of records also.
	      -j str : specify the key where the cursor jump to.
	      -rb bkey ekey : specify the range of keys.
	      -fm str : specify the prefix of keys.
	      -tz : enable the option `UINT8_MAX'.
	      -df : perform defragmentation only.
	      -sc : normalize keys as lower cases.
