- `kylin.query.lazy-query-enabled` 是否为短时间内重复发送的查询，等待并重用前次查询的结果，默认为 `false`。
- `kylin.query.cache-signature-enabled` 是否为缓存进行签名检查，依据签名变化来决定缓存的有效性。缓存的签名由项目中的 cube / hybrid 的状态以及它们的最后构建时间等来动态计算（在缓存被记录时）,默认为 `false`，高度推荐设置为 `true`。
- `kylin.query.segment-cache-enabled` 是否在 segment 级别缓存从 存储引擎(HBase)返回的数据，默认为 `false`；设置为 `true`，且启用 Memcached 分布式缓存开启的时候，此功能才会生效。可为频繁构建的 cube （如 streaming cube）提升缓存命中率，从而提升性能。

- `kylin.query.lazy-query-enabled` : whether to lazily answer the queries that be sent repeatedly in a short time (hold it until the previous query be returned, and then reuse the result); The default value is `false`.
- `kylin.query.cache-signature-enabled` : whether to use the signature of a query to determine the cache's validity. The signature is calculated by the cube/hybrid list of the project, their last build time and other information (at the moment when cache is persisted); It's default value is `false`, highly recommend to set it to `true`.
- `kylin.query.segment-cache-enabled` : whether to cache the segment level returned data (from HBase storage) into Memcached. This feature is mainly for the cube that built very frequently (e.g, streaming cube, whose last build time always changed a couple minutes, the whole SQL statement level cache is very likely be cleaned; in this case, the by-segment cache can reduce the I/O). This only works when Memcached configured, the default value is `false`.
