基于PostgreSQL的集群解决方案,同时适合OLTP 和OLAP应用。该项目的目标是整合Postgres-XC 和 Postgres-XL。
快速使用:
Init gtm, datanode, coordinator >initgtm -Z gtm -D gtm >initdb -D datanode1 --nodename dn1 #Initialize Datanode 1 >initdb -D datanode2 --nodename dn2 #Initialize Datanode 2 >initdb -D coord1 --nodename co1 # Initialize Coordinator 1 Change configuration *Show and check gtm.conf and each postgresql.conf, change port values for Datanodes => 15432 for Dn1, 15433 for Dn2 Node start-up >gtm -D gtm & >postgres -X -D datanode1 -i & # -X for a Datanode >postgres -X -D datanode2 -i & # -X for a Datanode >postgres -C -D coord1 -i & # -C for a Coordinator connect to coordinator >psql postgres launch that to set up cluster: >CREATE NODE dn1 WITH (TYPE='datanode', PORT=15432); >CREATE NODE dn2 WITH (TYPE='datanode', PORT=15433); >select * from pgxc_node; >select pgxc_pool_reload(); Then you can connect to Coordinator 1 and test your newly-made cluster
