/**
* aerospike::create(record)
* Function: udf_aerospike_rec_create
*
* Parameters:
* as - as_aerospike
* rec - as_rec
*
* Return Values:
* 1 if record is being read or on a create, it already exists
* o/w return value of udf_aerospike__execute_updates
*
* Description:
* Create a new record in local storage.
* The record will only be created if it does not exist.
* This assumes the record has a digest that is valid for local storage.
*
* Synchronization : object lock acquired by the transaction thread executing UDF.
* Partition reservation takes place just before the transaction starts executing
* ( look for as_partition_reserve_udf in thr_tsvc.c )
*
* Callers:
* lua interfacing function, mod_lua_aerospike_rec_create
* The return value of udf_aerospike_rec_create is pushed on to the lua stack
*
* Notes:
* The 'read' and 'exists' flag of udf_record are set to true.

/**
* aerospike::create(record)
* Function: udf_aerospike_rec_create
*
* Parameters:
* as - as_aerospike
* rec - as_rec
*
* Return Values:
* 1 if record is being read or on a create, it already exists
* o/w return value of udf_aerospike__execute_updates
*
* Description:
* Create a new record in local storage.
* The record will only be created if it does not exist.
* This assumes the record has a digest that is valid for local storage.
*
* Synchronization : object lock acquired by the transaction thread executing UDF.
* Partition reservation takes place just before the transaction starts executing
* ( look for as_partition_reserve_udf in thr_tsvc.c )
*
* Callers:
* lua interfacing function, mod_lua_aerospike_rec_create
* The return value of udf_aerospike_rec_create is pushed on to the lua stack
*
* Notes:
* The 'read' and 'exists' flag of udf_record are set to true.
