Hoss Man updated SOLR-6350:
---------------------------
Attachment: SOLR-6350.patch
Xu, your laast patch looked pretty good, but while review & tightening up the
tests i noticed a few more improvements.
I think this version is ready to commit.
Changes since last patch...
* alphabetize ive-versions.properties to make precommit happy
* added SHA1, LICENSE, and NOTICE for tdigest
* reverted unneccessary whitespace changes in CommonParams
* added some javadocs to FieldStatsInfo
* StatsField...
** switched from ArrayDigest to AVLTreeDigest per recomendations in the
t-digest docs
** renamed "compression" localparam to "tdigestCompression"
*** as an expert level op, we're assuming they know about the tdigets impl
details
** simplified tdigestCompression parsing to leverage SolrParam methods
** renamed "getGetTdigestCompression()" to "getTdigestCompression()"
** corrected getTdigestCompression() return type and local var to be double
(not int)
* StatsValuesFactory...
** use calculateStats & includeInResponse consistently like all other stats
** remove unused "protected Map<String,String> percentiles = new
LinkedHashMap<>()"
** fixed usage of "getGetTdigestCompression()" (new name, see above)
** eliminated smallByteSize() from the serialization logic in
addTypeSpecificStats (see comments)
* StatsComponentTest...
** testIndividualStatLocalParams
*** tightened assertions on individual percentile values
** testPercentiles
*** switched to using queryAndResponse so we don't need substring for janky xml
parsing
*** hardened asserts to ensure exact order of percentiles in response
*** simplified asserts that non-numerics don't support percentiles
* TestDistributedSearch...
** beefed up assertions
** included sanity testing of FieldStatsInfo.getPercentiles()
----
bq. We should see how we can share some of the implementation here.
That sounds like something that would be a much bigger scope then just
percentiles, and should be tracked in it's own Jira.
