Summary: Optimize decodeNumeric in OrderedBytes
Key: HBASE-26635
URL: https://issues.apache.org/jira/browse/HBASE-26635
Project: HBase
Issue Type: Improvement
Components: Performance
Reporter: Yutong Xiao
Assignee: Yutong Xiao
Currently, when we decode a byte array to a big decimal, there are plenty of
BigDecimal operations, which result in a lot of only once used BigDecimal
objects. Furthermore, the BigDecimal calculations are slow. We could boost this
function by using String concatenation and point movement of BigDecimal. The
JMH benchmark is uploaded to the attachment.
