Teonet database based at PBL KEYFILE: – C key file, C-KeyFile An open source C key file implementation, see pblKf functions

Features:

• ultra fast B* tree implementation for random lookups
• transaction handling
• sequential access methods
• embeddable small footprint, < 35 Kb
• arbitrary size files, up to 4 terrabytes
• arbitrary number of records per file, up to 2 ^ 48 records
• duplicate keys
• advanced key compression for minimal size B trees
• keylength up to 255 bytes
• regression test frame

The basic functions (commands) of the application:

• set - set data to namespace by key
• get - get data from namespace by key

whre:

• Namespace is a filename of PBL KEYFILE
• key is a duplicate key in PBL KEYFILE
• data is a data saved in PBL KEYFILE

API:

CMD_D_SET = 129, ///< #129 Set data request: { key, data, data_len, id } } CMD_D_GET, ///< #130 Get data request: { key, id } } CMD_D_LIST, ///< #131 List request: { key, id } } CMD_D_GET_ANSWER, ///< #132 Get data response: { key, data, data_len, id } } CMD_D_LIST_ANSWER, ///< #133 List response: [ { key, id }, ... ]

CMD_D_LIST_LENGTH, ///< #134 List length request: { key, id } } CMD_D_LIST_LENGTH_ANSWER, ///< #135 List response: { listLength, key, id }

CMD_D_LIST_RANGE, ///< #136 List length request: { id, key, from, to } } ///< bynary data structure: typedef struct teo_db_data_range { uint32_t from; ///< From index (begin from zero) uint32_t to; ///< To index (not include)) }; CMD_D_LIST_RANGE_ANSWER, ///< #137 List response: { listLength, key, ID }
