Repeated instant queries with long lookbehind windows, which contain one of the following rollup functions, are optimized via partial result caching: - sum_over_time() - count_over_time() - avg_over_time() - increase() - rate() The basic idea of optimization is to calculate rf(m[d] @ t) as rf(m[offset] @ t) + rf(m[d] @ (t-offset)) - rf(m[offset] @ (t-d)) where rf(m[d] @ (t-offset)) is cached query result, which was calculated previously The offset may be in the range of up to 1 hour. |
