> 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
> Priority: Major
> Fix For: 2.5.0, 3.0.0-alpha-3
>
> Attachments: Benchmark-decoding.log, DecodeBenchmark.java
>
>
> 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.
> Also, I added a UT to test the encoding / decoding correctness of 200 random
> test samples.
> The logic of the process is same as the Optimization of the encode function
> in the ticket [HBASE-26566|https://issues.apache.org/jira/browse/HBASE-26566]
