Tamanho total do cache do índice primário em bytes. Armazena índices de chave primária carregados sob demanda quando
primary_key_lazy_load=1 e use_primary_key_cache=1. As alocações ficam na arena dedicada do cache no jemalloc (jemalloc.cache_arena.*). NUNCA se sobrepõe a system.parts.primary_key_bytes_in_memory[_allocated] — o índice de uma parte fica ou neste cache (contabilizado aqui) ou na própria parte (contabilizado ali); nunca nos dois. Para obter a memória total do índice primário em todas as partes, some ambos.
