-------------------------------
Summary: optimize result transferring performance for scanning
short/null STRING values
Key: KUDU-1985
URL: https://issues.apache.org/jira/browse/KUDU-1985
Project: Kudu
Issue Type: Wish
Components: client, tserver
Reporter: DawnZhang
dear Kudu developers,
a string field cost at least 16 bytes in rows data while transferring scan
results
cpptype for STRING is kudu::Slice ( contains offset and size info ) and always
take 16bytes in row data sidecar.
when there are lots of short/null strings in scan result transferring via
network could be slow. ( compared with scanning parquet)
do you have any plan to optimize this?
