### Question
- skywalking会创建太多的索引库，我这里进行了代码修改，删除一天以前历史记录中文档数量为0的索引库。
### Requirement or improvement
- 修改代码：HistoryDeleteEsDAO .java
- long deadline2 = Long.parseLong(new
DateTime().plusDays(-1).toString("yyyyMMdd"));
- for (String index : indexes) {
long timeSeries =
TimeSeriesUtils.isolateTimeFromIndexName(index);
if (deadline >= timeSeries||(client.indexDocIsZero(tableName) &&
deadline2>= timeSeries)) {
prepareDeleteIndexes.add(index);
} else {
leftIndices.add(index);
}
}
-
修改代码：ElasticSearchClient.java
public boolean indexDocIsZero(String tableName) throws IOException {
SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
SearchRequest rq = new SearchRequest();
//索引
rq.indices(tableName);
//各种组合条件
rq.source(sourceBuilder);
//其实位置
sourceBuilder.from(0);
//每页数量
sourceBuilder.size(1);
SearchResponse search = client.search(rq);
return search.getHits().totalHits==0;
}
