Drill offers not just one, not just two, but three different representations of the query plan.
The first two can be had from the EXPLAIN PLAN statement. This is the textual form of the plan (shown in the query profile) and a near-complete JSON form. There is also a third form, with memory allocations filled in, but split into fragments, that can be found in the drillbit.log file. This form of the plan shows what actually executes in each minor fragment. - Paul > On Nov 10, 2017, at 6:48 AM, Muhammad Gelbana <[email protected]> wrote: > > Have a look at this page > <https://drill.apache.org/docs/performance-tuning-introduction/>.
