How to reduce write amplification when exists a few global index tables?

For real time writing scenario, the throughput will be  down when original table have more index table. According to the implement of secondary index,  how to accelerate writing speed?

You can use local indexes to reduce write amplification. In that case, all
index writes are local writes so the impact of multiple secondary indexes
is not as severe. Of course, there's a read penalty you'd pay, so make sure
you're ok with that.
