Galen O'Sullivan updated GEODE-2968:
------------------------------------
Component/s: rest (dev)
> Provide an API to set identity field(s) on JSON objects
> -------------------------------------------------------
>
> Key: GEODE-2968
> URL: https://issues.apache.org/jira/browse/GEODE-2968
> Project: Geode
> Issue Type: Improvement
> Components: rest (dev), serialization
> Reporter: Barry Oglesby
> Priority: Major
>
> I have a JSON object with 53 fields. The identity of that object is one
> specific field (the {{Unique_Key}} field in this case), but I can't specify
> that when loading the object. This causes {{PdxInstanceImpl equals}} and
> {{hashCode}} to use all 53 fields in their determinations and is especially
> bad for OQL queries.
> I hacked {{PdxInstanceHelper addIntField}} to set an identity field like:
> {noformat}
> if (fieldName.equals("Unique_Key")) {
> m_pdxInstanceFactory.markIdentityField(fieldName);
> }
> {noformat}
> Here are some queries before and after this change:
> Before:
> {noformat}
> Totals query=SELECT * FROM /data WHERE Agency = 'NYPD'; resultSize=1890;
> iterations=1000; totalTime=30529 ms; averagePerQuery=30.529 ms
> Totals query=SELECT * FROM /data WHERE Incident_Address LIKE '%AVENUE%';
> resultSize=2930; iterations=1000; totalTime=62723 ms; averagePerQuery=62.723
> ms
> Totals query=SELECT * FROM /data; resultSize=10000; iterations=1000;
> totalTime=87673 ms; averagePerQuery=87.673 ms
> {noformat}
> After:
> {noformat}
> Totals query=SELECT * FROM /data WHERE Agency = 'NYPD'; resultSize=1890;
> iterations=1000; totalTime=12417 ms; averagePerQuery=12.417 ms
> Totals query=SELECT * FROM /data WHERE Incident_Address LIKE '%AVENUE%';
> resultSize=2930; iterations=1000; totalTime=29517 ms; averagePerQuery=29.517
> ms
> Totals query=SELECT * FROM /data; resultSize=10000; iterations=1000;
> totalTime=44127 ms; averagePerQuery=44.127 ms
> {noformat}
