记录在聚合周期内,相同聚合主键的查询的duration、memory_bytes、cpu_time_ms、physical_reads、optimization_cost、start_query_cost、get_next_cost等数值字段的MIN、MAX、AVG等统计值。 extended_info JSONB 其他扩展信息。记录Query Queue、Serverl
[out] pullMaxNumberOfReclaimableBytes 成功完成時,變數的指標會收到可從目前磁碟區回收的最大位元元組數目。 這個數位一律會是文件系統叢集大小的倍數,也就是磁碟扇區大小的倍數。 這個參數是必要的,而且不能是 null。 傳回值 這個方法可以傳回標準 HRESULT 值,例如E_INVALIDARG或E_OUTOFMEMORY,以及VDS 特定...

Qcache_free_memory: Total bytes of memory free in the query cache Qcache_hits: Number of times a query matched the query cache Qcache_inserts: Number of times a query and result set were inserted into the query cache Qcache_lowmem_prunes: Number of times a query was removed due to query...
...这是一个很容易混淆的问题,我们来看一下一个貌似很合理的解释: x stores the reference which points to the "ab" string in the heap...真正的代码执行过程应该是这样的: When the string "ab" is created, Java allocates the amount of memory required to store...当string变量‘ab’被创建出来的...
Memory overhead is about 32 bytes per document + ≈4-16 bytes per each search index. There is an object cache on the Go level for deserialized documents produced after query execution. Future queries use pre-deserialized documents, which cuts repeated deserialization and allocation costs The Quer...
In most cases, the Query executor exceeded total memory limitation xxxxx: yyyy bytes used error message is reported. Import efficiency is low. When you query or import data in Hologres, the efficiency of the system decreases and tasks take longer than expected to complete. Set an appro...
