## What changes were proposed in this pull request? 1.In `acquireStorageMemory`, when the Memory Mode is OFF_HEAP ,the `maxOffHeapMemory` should be modified to `maxOffHeapStorageMemory`. after this PR,it will same as ON_HEAP Memory Mode. Because when acquire memory is between `maxOffHeapStorageMemory` and `maxOffHeapMemory`,it will fail surely, so if acquire memory is greater than `maxOffHeapStorageMemory`(not greater than `maxOffHeapMemory`),we should fail fast. 2. Borrow memory from execution, `numBytes` modified to `numBytes - storagePool.memoryFree` will be more reasonable. Because we just acquire `(numBytes - storagePool.memoryFree)`, unnecessary borrowed `numBytes` from execution ## How was this patch tested? added unit test case Author: liuxian <liu.xian3@zte.com.cn> Closes #18296 from 10110346/wip-lx-0614. |
