Citus replication model

[huseynsnmz]

Hello,

I saw "citus.replication_model" parameter in issue pages and I couldn't find any information in documents. I find description in PostgreSQL settings but I couldn't understand what it is used for. What is the difference between citus.replication_model = 'statement and citus.replication_model = 'streaming' ?

Difference in functionality: Citus Blog (very useful, recommended)

Difference as restrictions: streaming mode can only be used when citus.shard_replication_factor = 1 and only if you use hash distribution. And it's not allowed for deprecated master_create_distributed_table. While statement is allowed with greater replication factors and other distribution methods.

see create_distributed_table.c
