Re: PostgreSQL high availability solutions for high rates.

Hi to the PostgreSql Admin community,

 

we are evaluating PostgreSQL for our productions, for a system with 1000 updates per second,1000 inserts per sec, ~1000 deletes per second1,

250,000 transactions per day,  writing ~200+GB   day, 200+gb wall per day,  and deleting ~80-100GB  per day.

 

we are looking for “active-active (r/w) (r/w)”  ,  “active(r/w) -active(read) “

and “active(r/w) stand-by”  high availability solution,

what High availability solutions ( PG internal or 3rd party) are  used successfully, keeping up   with the similar rates? double of those rates?

do we need 3^rd party software solution or can use postgreSQL replication solution alone? ( or combinations?)

 

do we have benchmark papers comparing alternatives?

 

thanks in advance, Aliza.
