Based on the latest master code implementation,
MemoryReclamation::revoke_tasks_memoryis responsible for reclaiming memory used
by SQL queries. It filters SQL queries based on the input filters, which
includes filtering out queries with memory consumption less than 32MB.
```
int64_t MemoryReclamation::revoke_tasks_memory(
int64_t need_free_mem, const
std::vector<std::shared_ptr<ResourceContext>>& resource_ctxs,
const std::string& revoke_reason, RuntimeProfile* profile,
PriorityCmpFunc priority_cmp,
std::vector<FilterFunc> filters, ActionFunc action) {
---
for (auto filter : filters) {
if (!FilterFuncImpl[filter](resource_ctx.get())) {
is_filtered = true;
break;
}
}
if (is_filtered) {
continue;
}
---
{FilterFunc::EXCLUDE_IS_SMALL,
[](ResourceContext* resource_ctx) {
return resource_ctx->memory_context()->current_memory_bytes() >
SMALL_MEMORY_TASK;
}}
```
