Hi <br /><br />I am not sure but liferay already have cache implementation using Ehcache so for each entity we can use cache mechanism <br /><br /><br />the following is info from service builder DTD<br /><br /><br /><a href="https://github.com/liferay/liferay-portal/blob/master/definitions/liferay-service-builder_6_2_0.dtd">https://github.com/liferay/liferay-portal/blob/master/definitions/liferay-service-builder_6_2_0.dtd</a><br /><br />The cache-enabled value specifies whether or not to cache this queries for this<br />entity.

Hi,<br />I would like to know Liferay cache system.<br />I have to get all liferay users along with social equity points and save them in cache( suppose 70,000 users).<br />External systems use web service to get x(5000) number of users details,then it should fetch data from cache and return back.<br /><br />Can anybody suggests me how can i implement caching for the above scenario?
