Hi,
If a query is executed against a fully REPLICATED data then Ignite will send it to a single cluster node and run it over the local data there. if a query is executed over a PARTITIONED data, then the execution flow will be the following: The query will be parsed and split into multiple map queries and a single reduce query. * All the map queries are executed on all the nodes where required data resides. * All the nodes provide result sets of local execution to the query initiator (reducer) that, in turn, will accomplish the reduce phase by properly merging provided result sets. More information here: https://apacheignite-sql.readme.io/docs/how-ignite-sql-works Thanks, Alex From: Prasad Bhalerao <prasadbhalerao1...@gmail.com> Sent: Friday, October 25, 2019 1:31 AM To: user@ignite.apache.org Subject: Query execution in ignite Hi, When SQL is executed, does ignite always scan only primary partitions of all available nodes in cluster irrespective of cache mode partitioned or replicated? Thanks , Prasad
