### Is your feature request related to a problem or challenge? When running an external query with `TrackConsumersPool`, when the memory pool runs out of memory and the error is unrecoverable, top memory consumers are displayed to help debug. ```sh # set memory limit to 20M and use a `TrackConsumersPool` wrapper > select * from generate_series(1,500000000) as t1(v1) order by v1; Resources exhausted: Additional allocation failed with top memory consumers (across reservations) as: ExternalSorterMerge[0]#2(can spill: false) consumed 31416320 bytes, DataFusion-Cli#0(can spill: false) consumed 0 bytes. Error: Failed to allocate additional 66560 bytes for ExternalSorterMerge[0] with 0 bytes already allocated for this reservation - 40960 bytes remain available for the total pool ``` To make the error message format better, I suggest to 1. Break each consumer to a single line 2. Use human readbale memory size https://github.com/apache/datafusion/blob/7a3d020af2a3736db11ba7477efc1a5dae96c2d3/datafusion/execution/src/memory_pool/mod.rs#L425 ``` Resources exhausted: Additional allocation failed with top memory consumers (across reservations) as: ExternalSorterMerge[0]#2(can spill: false) consumed 3.1MB, DataFusion-Cli#0(can spill: false) consumed 0 bytes. Error: Failed to allocate additional 66KB for ExternalSorterMerge[0] with 0 bytes already allocated for this reservation - 40KB remain available for the total pool ``` ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
