Hi

In GemFire which query type is more optimized or faster

Object[] params = new Object[1];

  params[0] =mykey.getData;

CacheFactory.getAnyInstance().getQueryService().newQuery("select * from /myregion where data = $1").execute(params);

or

CacheFactory.getAnyInstance().getQueryService().newQuery("select * from /myregion where data =" +mykey.getData).execute(params);
