This patch clear the ambiguity in the swagger definition file and adds
the implementation for the memtable memory related methods.
For each column family there is an active memtable and a list of non
active.
when refering the all the memtable in the column family, the nick name
will contain cf_all_memtables.
Each URL has two versions, one, with a column family name, that is
relevant to a specific column family and one without, which is the
result of running the method on all column families.
This patch adds the following implementation to column_family:
get_memtable_on_heap_size
get_all_memtable_on_heap_size
get_memtable_off_heap_size
get_all_memtable_off_heap_size
get_memtable_live_data_size
get_all_memtable_live_data_size
get_all_memtables_on_heap_size
get_all_all_memtables_on_heap_size
get_all_memtables_off_heap_size
get_all_all_memtables_off_heap_size
get_all_memtables_live_data_size
get_all_all_memtables_live_data_size
Memory consumption is map this way: All memory assume to be off heap, so
on heap will return 0, and off heap will return the memory consumption
After this patch the following URL will be available:
/column_family/metrics/memtable_on_heap_size/{name}
/column_family/metrics/memtable_on_heap_size
/column_family/metrics/memtable_off_heap_size/{name}
/column_family/metrics/memtable_off_heap_size
/column_family/metrics/memtable_live_data_size/{name}
/column_family/metrics/memtable_live_data_size
/column_family/metrics/all_memtables_on_heap_size/{name}
/column_family/metrics/all_memtables_on_heap_size
/column_family/metrics/all_memtables_off_heap_size/{name}
/column_family/metrics/all_memtables_off_heap_size
/column_family/metrics/all_memtables_live_data_size/{name}
/column_family/metrics/all_memtables_live_data_size
