run an [atomic `merge` statement](https://docs.databricks.com/en/sql/language-manual/delta-merge-into.html) which looks nearly identical to the default merge behavior on Snowflake and BigQuery. +If a `unique_key` is specified (recommended), dbt will update old records with values from new records that match on the key column. +If a `unique_key` is not specified, dbt will forgo match criteria and simply insert all new records (similar to `append` strategy). + +Specifying `merge` as the incremental strategy is optional since it's the default strategy used when none is specified. + +From v.1.9 onwards `merge` behavior can be tuned by setting the additional parameters. + +- Merge steps control parameters that tweak the default behaviour: + - `skip_matched_step`: if set to `true`, dbt will completely skip the `matched` clause of the merge statement. + - `skip_not_matched_step`: similarly if `true` the `not matched` clause will be skipped. + - `not_matched_by_source_action`: if set to `delete` the corresponding `when not matched by source ... then delete` clause will be added to the merge statement. + - `merge_with_schema_evolution`: when set to `true` dbt generates the merge statement with `WITH SCHEMA EVOLUTION` clause. + +- Step conditions that are expressed with an explicit SQL predicates allow to execute corresponding action only in case the conditions are met in addition to matching by the `unique_key`. + - `matched_condition`: applies to `when matched` step. + In order to define such conditions one may use `tgt` and `src` as aliases for the target and source tables respectively, e.g. `tgt.col1 = hash(src.col2, src.col3)`. + - `not_matched_condition`: applies to `when not matched` step. + - `not_matched_by_source_condition`: applies to `when not matched by source` step. + - `target_alias`, `source_alias`: string values that will be used instead of `tgt` and `src` to distinguish between source and target tables in the merge statement. + +Example below

This may have more latency but will not truncate complex data types the way that 'describe' can.

`expression` as the constraint (thanks @roydobbe). ([792](https://github.com/databricks/dbt-databricks/pull/792)) - Add "use_info_schema_for_columns" behavior flag to turn on use of information_schema to get column info where possible. This may have more latency but will not truncate complex data types the way that 'describe' can. ([808](https://github.com/databricks/dbt-databricks/pull/808)) - Add support for table_format: iceberg. This uses UniForm under the hood to provide iceberg compatibility for tables or incrementals. ([815](https://github.com/databricks/dbt-databricks/pull/815)) +- Add `include_full_name_in_path` config boolean for external locations. This writes tables to {location_root}/{catalog}/{schema}/{table} ([823](https://github.com/databricks/dbt-databricks/pull/823)) - Add a new `workflow_job` submission method for python, which creates a long-lived Databricks Workflow instead of a one-time run (thanks @kdazzle!) ([762](https://github.com/databricks/dbt-databricks/pull/762)) - Allow for additional options to be passed to the Databricks Job API when using other python submission methods.
