Bin memory Management of Aerospike-column memory Management

1. Memory request function call

Write_master- > write_master_dim- > write_master_bin_ops

-> write_master_bin_ops_loop- > as_bin_particle_alloc_from_client:

This function requests memory from as_bin_s- > particle and load the relevant bin attributes and values to the

In the requested memory.

2. Memory release function call

As_record_done- > as_record_destroy- > as_record_clean_bins

-> as_record_clean_bins_from
