Method Details

createIfMissing

public CompletableFuture<?> createIfMissing(OperationSubmitter operationSubmitter)

Description copied from interface: IndexSchemaManager

Creates the schema if it doesn't already exist.

Does not change or validate anything if the schema already exists.

Specified by:

createIfMissing in interface IndexSchemaManager

Parameters:

operationSubmitter - How to handle request to submit operation when the queue is full.

Returns:

A future.

createOrValidate

public CompletableFuture<?> createOrValidate(ContextualFailureCollector failureCollector,
 OperationSubmitter operationSubmitter)

Description copied from interface: IndexSchemaManager

Creates the schema if it doesn't already exist, or validates the existing schema against requirements expressed by the mapper.

If the schema exists and validation happens, validation failures do not trigger an exception, but instead are pushed to the given collector.

Specified by:

createOrValidate in interface IndexSchemaManager

Parameters:

failureCollector - A collector for validation failures.

operationSubmitter - How to handle request to submit operation when the queue is full.

Returns:

A future.

createOrUpdate

public CompletableFuture<?> createOrUpdate(OperationSubmitter operationSubmitter)

Description copied from interface: IndexSchemaManager

Creates the schema if it doesn't already exist, or updates the existing schema to match requirements expressed by the mapper.

Updating the schema may be impossible (for example if the type of a field changed). In this case, the future will ultimately be completed with a SearchException.

Specified by:

createOrUpdate in interface IndexSchemaManager

Parameters:

operationSubmitter - How to handle request to submit operation when the queue is full.

Returns:

A future.

dropIfExisting

public CompletableFuture<?> dropIfExisting(OperationSubmitter operationSubmitter)

Description copied from interface: IndexSchemaManager

Drops the schema and all indexed data if it exists.

Does not change anything if the schema does not exist.

Specified by:

dropIfExisting in interface IndexSchemaManager

Parameters:

operationSubmitter - How to handle request to submit operation when the queue is full.

Returns:

A future.

dropAndCreate

public CompletableFuture<?> dropAndCreate(OperationSubmitter operationSubmitter)

Description copied from interface: IndexSchemaManager

Drops the schema and all indexed data if it exists, then creates the schema.

Specified by:

dropAndCreate in interface IndexSchemaManager

Parameters:

operationSubmitter - How to handle request to submit operation when the queue is full.

Returns:

A future.

validate

public CompletableFuture<?> validate(ContextualFailureCollector failureCollector,
 OperationSubmitter operationSubmitter)

Description copied from interface: IndexSchemaManager

Validates the existing schema against requirements expressed by the mapper.

If the schema does not exist, a failure is pushed to the given collector.

If the index exists and validation happens, validation failures do not trigger an exception, but instead are pushed to the given collector.

Specified by:

validate in interface IndexSchemaManager

Parameters:

failureCollector - A collector for validation failures.

operationSubmitter - How to handle request to submit operation when the queue is full.

Returns:

A future.

exportExpectedSchema

public void exportExpectedSchema(IndexSchemaCollector collector)

Description copied from interface: IndexSchemaManager

Accepts a collector that will receive the schema export represented by this index schema manager.

Specified by:

exportExpectedSchema in interface IndexSchemaManager

computeSizeInBytes

public CompletableFuture<Long> computeSizeInBytes(OperationSubmitter operationSubmitter)
