From 593992312a8b7fec6557df8eed48ba7c0ff256bc Mon Sep 17 00:00:00 2001 From: Samir Patel Date: Fri, 24 Jun 2022 14:00:14 -0500 Subject: [PATCH] increase time range for timestamp by using specified granularity previously we allowed users to specify a granularity for timestamp e.g. seconds, milli, micro, nano however we converted everything to nano before we stored it. This reduced the allowed range for all time units to what was allowed by timestamp. For example, with second granularity you can represent billions of years within the capacity of int64 but with nano its somewhere b/w 100-200 years. So now, for timeunits of seconds, milli, and micro the range is year 0001 - 9999. These limits come from what Go supports. So this uses unit specific function to translate timestamps to values and vice versa to increase the time range. --- api.go | 2 +- api_test.go | 84 ++++----- executor.go | 67 +++++++- executor_test.go | 438 ++++++++++++++++++++++++++++++++++++++++++++++- field.go | 130 +++++++++----- field_test.go | 71 ++++---- server/pg.go | 8 +- util.go | 6 +- util_test.go | 34 ++-- 9 files changed, 684 insertions(+), 156 deletions(-) diff --git a/api.go b/api.go index 66fdfb8f5..400deb995 100644 --- a/api.go +++ b/api.go @@ -2006,7 +2006,7 @@ func (api *API) IngestOperations(ctx context.Context, qcx *Qcx, indexName string return fmt.Errorf("adding decimal field to codec: %w", err) } case "timestamp": -
