From 90400ead05e6daa8c1c19961464d7b1884a73cf3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Strzali=C5=84ski?= Date: Wed, 16 Oct 2024 15:17:03 +0200 Subject: [PATCH] Table resolver - apply decision (#870) This is second part of the table resolver introduction. In this PR: 1. Decisions made by resolved are applied. 2. Some rules were simplified 3. Add test. 4. Add endpoint `/index:/_quesma_table_resolver` to get a decision (it will be used in e2e tests) ``` curl 'http://localhost:8080/logs*/_quesma_table_resolver ```` Limitations: - Table name overrides are handled as before. - Rules may be incorrect. Tests are passing. But this is complex rewrite. --------- Co-authored-by: Piotr Grabowski --- http_requests/disabled.http | 6 + http_requests/table_resolver.http | 1 + quesma/elasticsearch/index_management.go | 38 +++
