[jira] [Created] (IGNITE-4511) Set QueryIndexType.SORTED by default
for an index
Steve Hostettler created IGNITE-4511:
----------------------------------------
Summary: Set QueryIndexType.SORTED by default for an index
Key: IGNITE-4511
URL: https://issues.apache.org/jira/browse/IGNITE-4511
Project: Ignite
Issue Type: Improvement
Affects Versions: 1.7
Environment: Windows Server + Java 8
Reporter: Steve Hostettler
Priority: Minor
The code snippet below creates a index of type FULL TEXT which much slower and that I do not need;
QueryIndex idx1 = new QueryIndex();
LinkedHashMap<String, Boolean> idxFlds1 = new LinkedHashMap<>();
idxFlds1.put("field1", true);
idxFlds1.put("field2", true);
idx1.setFields(idxFlds1);
idxs.add(idx1);
To avoid this I must explicitly set
idx1.setIndexType(QueryIndexType.SORTED);
This is because with the above code snippet, the Index Type is null and that null is interpreted as FULL TEXT in GridQueryProcessor.java
if (idx.getIndexType() == QueryIndexType.SORTED || idx.getIndexType() == QueryIndexType.GEOSPATIAL) {
....
} else {
assert idx.getIndexType() == QueryIndexType.FULLTEXT;
for (String field : idx.getFields().keySet()) {
String alias = aliases.get(field);
if (alias != null)
field = alias;
d.addFieldToTextIndex(field);
}
}
