be synchronous? • If sharding across multiple instances: – Will you have distributed transactions? – Do you require distributed consistency? – What isolation level is being used? • Will there be a node in 9.6: Parallel Query • Prior to 9.6, if you had a 32 core system, needed to run one large query, and you were the only user on the system, that query would still just utilize one single core, with OLAP • OLTP write and read scalability • Custer-wide ACID properties • Can also act as distributed key-value store • Currently based on PostgreSQL 9.5 Postgres Conference China 2016 中国用户大会
