Implement offset operator. This allows changing the time offset for individual instant and range vectors in a query. For example, this returns the value of `foo` 5 minutes in the past relative to the current query evaluation time: foo offset 5m Note that the `offset` modifier always needs to follow the selector immediately. I.e. the following would be correct: sum(foo offset 5m) // GOOD. While the following would be *incorrect*: sum(foo) offset 5m // INVALID. The same works for range vectors. This returns the 5-minutes-rate that `foo` had a week ago: rate(foo[5m] offset 1w) This change touches the following components: * Lexer/parser: additions to correctly parse the new `offset`/`OFFSET` keyword. * AST: vector and matrix nodes now have an additional `offset` field. This is used during their evaluation to adjust query and result times appropriately. * Query analyzer: now works on separate sets of ranges and instants per offset. Isolating different offsets from each other completely in this way keeps the preloading code relatively simple. No storage engine changes were needed by this change. The rules tests have been changed to not probe the internal implementation details of the query analyzer anymore (how many instants and ranges have been preloaded). This would also become too cumbersome to test with the new model, and measuring the result of the query should be sufficient. This fixes https://github.com/prometheus/prometheus/issues/529 This fixed https://github.com/prometheus/promdash/issues/201

For example, this returns the value of `foo` 5 minutes in the past relative to the current query evaluation time: foo offset 5m Note that the `offset` modifier always needs to follow the selector immediately. I.e. the following would be correct: sum(foo offset 5m) // GOOD. While the following would be *incorrect*: sum(foo) offset 5m // INVALID. The same works for range vectors. This returns the 5-minutes-rate that `foo` had a week ago: rate(foo[5m] offset 1w) This change touches the following components: * Lexer/parser: additions to correctly parse the new `offset`/`OFFSET` keyword. * AST: vector and matrix nodes now have an additional `offset` field. This is used during their evaluation to adjust query and result times appropriately. * Query analyzer: now works on separate sets of ranges and instants per offset. Isolating different offsets from each other completely in this way keeps the preloading code relatively simple. No storage engine changes were needed by this change. The rules tests have been changed to not probe the internal implementation details of the query analyzer anymore (how many instants and ranges have been preloaded). This would also become too cumbersome to test with the new model, and measuring the result of the query should be sufficient. This fixes https://github.com/prometheus/prometheus/issues/529 This fixed https://github.com/prometheus/promdash/issues/201

Implement offset operator. This allows changing the time offset for individual instant and range vectors in a query. For example, this returns the value of `foo` 5 minutes in the past relative to the current query evaluation time: foo offset 5m Note that the `offset` modifier always needs to follow the selector immediately. I.e. the following would be correct: sum(foo offset 5m) // GOOD. While the following would be *incorrect*: sum(foo) offset 5m // INVALID. The same works for range vectors. This returns the 5-minutes-rate that `foo` had a week ago: rate(foo[5m] offset 1w) This change touches the following components: * Lexer/parser: additions to correctly parse the new `offset`/`OFFSET` keyword. * AST: vector and matrix nodes now have an additional `offset` field. This is used during their evaluation to adjust query and result times appropriately. * Query analyzer: now works on separate sets of ranges and instants per offset. Isolating different offsets from each other completely in this way keeps the preloading code relatively simple. No storage engine changes were needed by this change. The rules tests have been changed to not probe the internal implementation details of the query analyzer anymore (how many instants and ranges have been preloaded). This would also become too cumbersome to test with the new model, and measuring the result of the query should be sufficient.

Implement offset operator. This allows changing the time offset for individual instant and range vectors in a query. For example, this returns the value of `foo` 5 minutes in the past relative to the current query evaluation time: foo offset 5m Note that the `offset` modifier always needs to follow the selector immediately. I.e. the following would be correct: sum(foo offset 5m) // GOOD. While the following would be *incorrect*: sum(foo) offset 5m // INVALID. The same works for range vectors. This returns the 5-minutes-rate that `foo` had a week ago: rate(foo[5m] offset 1w) This change touches the following components: * Lexer/parser: additions to correctly parse the new `offset`/`OFFSET` keyword. * AST: vector and matrix nodes now have an additional `offset` field. This is used during their evaluation to adjust query and result times appropriately. * Query analyzer: now works on separate sets of ranges and instants per offset. Isolating different offsets from each other completely in this way keeps the preloading code relatively simple. No storage engine changes were needed by this change.

Implement offset operator. This allows changing the time offset for individual instant and range vectors in a query. For example, this returns the value of `foo` 5 minutes in the past relative to the current query evaluation time: foo offset 5m Note that the `offset` modifier always needs to follow the selector immediately. I.e. the following would be correct: sum(foo offset 5m) // GOOD. While the following would be *incorrect*: sum(foo) offset 5m // INVALID. The same works for range vectors. This returns the 5-minutes-rate that `foo` had a week ago: rate(foo[5m] offset 1w) This change touches the following components: * Lexer/parser: additions to correctly parse the new `offset`/`OFFSET` keyword. * AST: vector and matrix nodes now have an additional `offset` field. This is used during their evaluation to adjust query and result times appropriately. * Query analyzer: now works on separate sets of ranges and instants per offset. Isolating different offsets from each other completely in this way keeps the preloading code relatively simple. No storage engine changes were needed by this change. The rules tests have been changed to not probe the internal implementation details of the query analyzer anymore (how many instants and ranges have been preloaded). This would also become too cumbersome to test with the new model, and measuring the result of the query should be sufficient.
