Alright we got the messages seperated into chunks for the keys
tonight. Using the below it will separate the message into chunks
suitable for the keys.
while(buf_pos < msg_size+1){
if(buf_pos % KVCHUNK_SIZE == 0&&buf_pos !=0){
msg_buff[key_num][cbuf_pos]='';
key_num++;
cbuf_pos=0;
msg_buff[key_num][cbuf_pos]=buf[buf_pos];
}else{
msg_buff[key_num][cbuf_pos]=buf[buf_pos];
}
cbuf_pos++;
buf_pos++;
}
I'm trying to get bzip compression to work but it keeps returning a
-8(output buffer is full). Because I have a good feeling that 25-50%
of the mail can be compressed into one key. Unless its a 20MB chunk or
compressed base64 mime data then it turns into 11651 keys. Then I
don't think its feasible to use memcache, but to lay to load back to
the sql server for processing
I am trying to use the bzip2 library like so to compress the buffer.
char *cbuf=malloc(sizeof(*buf));
size_t cbuf_size=0;
int
ret=BZ2_bzBuffToBuffCompress(cbuf,&cbuf_size,buf,(size_t)strlen(buf),9,4,30);
printf("COMPRESSED MSG:nRETURN VALUE: %dnORIGINAL
SIZE:%dnDATA:%snCOMPRESS
SIZE:%dnDATA:%sm",ret,strlen(buf),buf,cbuf_size,cbuf);
free(cbuf);
It always returns a -8 anyone know what I am doing wrong here?
I know I am adding alot of processing into dbmail and that it takes
the load and places more on dbmail and memcache instead of mysql, I
think this might be the ticket though in a multi server cloud farm
where there is one mysql, instead of adding replicating mysql servers
you would only need to add memcache servers then clones of the mail
servers.
