Detailed Description

Factory class for generating table requirements.

This class analyzes a sequence of table updates and generates the appropriate table requirements to ensure safe concurrent modifications.

Member Function Documentation

ForCreateTable()

Result< std::vector< std::unique_ptr< TableRequirement > > > iceberg::TableRequirements::ForCreateTable ( const std::vector< std::unique_ptr< TableUpdate > > &  table_updates )

static

Generate requirements for creating a new table.

For table creation, this requires that the table does not already exist.

Parameters

table_updates

The list of table updates for table creation

Returns

A list of table requirements to validate before creation

ForReplaceTable()

Result< std::vector< std::unique_ptr< TableRequirement > > > iceberg::TableRequirements::ForReplaceTable ( const TableMetadata &  base, const std::vector< std::unique_ptr< TableUpdate > > &  table_updates  )

static

Generate requirements for replacing an existing table.

For table replacement, this requires that the table UUID matches but allows more aggressive changes than a regular update.

Parameters

base	The base table metadata
table_updates	The list of table updates for replacement

Returns

A list of table requirements to validate before replacement

ForUpdateTable()

Result< std::vector< std::unique_ptr< TableRequirement > > > iceberg::TableRequirements::ForUpdateTable ( const TableMetadata &  base, const std::vector< std::unique_ptr< TableUpdate > > &  table_updates  )

static

Generate requirements for updating an existing table.

For table updates, this generates requirements to ensure that key metadata properties haven't changed concurrently.

Parameters

base	The base table metadata
table_updates	The list of table updates

Returns

A list of table requirements to validate before update
