Hi Guy's
I need small help on PostgreSQL testing of HA
I am trying to run pgbench but once the primary goes down and secondary comes primary , I want to know know how I can configute pgbench to retry and autoconnect the pgbench workload which I have been running to new Primary .
the idea is to test the Retry feature of pgbench if it exists .
Is pgbeach has Retry fetaure ? if yes then what is parameter for retry needs commands .
can you please help and provide the direction and link
Thanks
Pradeep

periodically get swapped out entirely (i.e. lots of dead rows), indexes slowly degrade, pushing query latency up. Is there a way to detect this condition short of just monitoring statement latency, so as to know when to REINDEX / build new indexes? -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ |
