Function Documentation

◆ add_pke()

bool add_pke ( TABLE table,
THD thd,
const uchar record 
)

Function to add the hash of the PKE to the transaction context object.

Parameters
[in]table- TABLE object
[in]thd- THD object pointing to current thread.
[in]record- The record to process (record[0] or record[1]).
Returns
true if an issues exists adding the pke, false otherwise

◆ debug_check_for_write_sets()

static void debug_check_for_write_sets ( std::vector< std::string > &  key_list_to_hash,
std::vector< uint64 > &  hash_list 
)
static

◆ generate_hash_pke()

static bool generate_hash_pke ( const std::string &  pke,
THD thd,
std::vector< std::string > &  write_sets,
std::vector< uint64 > &  hash_list 
)
static

Function to generate the hash of the string passed to this function.

Parameters
[in]pke- the string to be hashed.
[in]thd- THD object pointing to current thread.
Returns
true if a problem occurred on generation or write set tracking.
Parameters
[in]write_sets- list of all write sets
[in]hash_list- list of all hashes

◆ generate_mv_hash_pke()

static bool generate_mv_hash_pke ( const std::string &  prefix_pke,
THD thd,
Field fld,
std::vector< std::string > &  write_sets,
std::vector< uint64 > &  hash_list 
)
static

Function to generate set of hashes for a multi-valued key.

Parameters
[in]prefix_pke- stringified non-multi-valued prefix of key
[in]thd- THD object pointing to current thread.
[in]fld- multi-valued keypart's field
Returns
true if a problem occurred on generation or write set tracking.
Parameters
[in]write_sets- DEBUG ONLY, vector of added PKEs
[in]hash_list- DEBUG ONLY, list of all hashes
