Javier Jaramago Fernández	4ee5c8bdde	Improve recovery (OFFLINE_HARD) optimization for GR autodiscovered servers ... In case an autodiscovered server is found 'OFFLINE_HARD', the recovery logic now properly updates the 'servers_defaults' values for the server, in the same way as for a new discovered server.	3 years ago

Rahim Kanji	aaa959d024	Refactor and optimize read-only actions method ... This commit optimizes the read-only actions method by removing the dependency on proxysql admin tables. Instead, a separate mapping container is maintained, which records the state of the HGM servers. This avoids the need to call the commit method on every change, which improves performance. The changes in this commit also ensure that the mapping container is properly updated when servers are added, removed or modified.	3 years ago

René Cannaò	eac6e75dad	Adding a simulator for read_only test ... This commit introduces a first simulator for read_only monitoring ProxySQL itself will simulate hundreds of backends across hundreds of hostgroups, all configured in hundreds of clusters, and return read_only values for each of the simulated backend. The read_only value can be configured in table READONLY_STATUS available in the SQLite3Server module. If a backend isn't configured in table READONLY_STATUS , its default read_only value is 1. It is possible to simulate a lot of simultaneous failover running queries like the following: UPDATE READONLY_STATUS SET read_only=1; CREATE TABLE t1 AS SELECT hostname FROM READONLY_STATUS ORDER BY RANDOM() LIMIT 50; UPDATE READONLY_STATUS SET read_only=0 WHERE hostname IN (SELECT hostname FROM t1); DROP TABLE t1;	5 years ago
