• SupportsOverwrite (Spark SQL)
• SupportsTruncate (Spark SQL)
• V1WriteBuilder (Spark SQL)

Creating Instance¶

WriteIntoDeltaBuilder takes the following to be created:

• DeltaLog
• Write-Specific Options

WriteIntoDeltaBuilder is created when:

• DeltaTableV2 is requested for a WriteBuilder

buildForV1Write¶

buildForV1Write(): InsertableRelation

buildForV1Write is part of the V1WriteBuilder (Spark SQL) abstraction.

buildForV1Write creates an InsertableRelation (Spark SQL) that does the following when requested to insert:

1. Creates and executes a WriteIntoDelta command
2. Re-cache all cached plans (by requesting the CacheManager to recacheByPlan for a LogicalRelation over the BaseRelation of the DeltaLog)
