What changes are included in this PR?
This pr adds some microbenchmarks to compare performance characteristics between different compression codecs. It generates 50 RecordBatch for each case, and run both write & read. It manually prints out compression ratio (mem_bytes / disk_bytes) after each run.
To make benchmark more realistic, this pr generates
RecordBatches
that resemble the data it spills onAggregateExec
(tpc-h) andSortExec
(sort-tpch). It covers both thin batch consists of primitive arrays and wide batches with complex data type.Rationale for this change
Benchmark Case Overview
Below are schema of RecordBatch & original query for each benchmark case.
Are these changes tested?
Are there any user-facing changes?
