> SQL: DML should not use batches by default
> ------------------------------------------

> Key: IGNITE-11499
> URL: https://issues.apache.org/jira/browse/IGNITE-11499
> Project: Ignite
> Issue Type: Task
> Components: sql
> Reporter: Vladimir Ozerov
> Assignee: Taras Ledkov
> Priority: Major
> Fix For: 2.8

> Time Spent: 20m
> Remaining Estimate: 0h

> Currently DML apply updates in batches equal to {{SqlFieldsQuery.pageSize}}.
> This is prone to deadlocks. Instead, we should apply updates one-by-one by
> default. Proposal:
> # Introduce {{SqlFieldsQuery.updateBatchSize}} property, set it to {{1}} by
> default
> # Print a warning about deadlock to log if it is greater than 1
> # Add it to JDBC and ODBC drivers
> # Add it to other languages
