Class SSTableHeaderFix.Builder

java.lang.Object

org.apache.cassandra.io.sstable.SSTableHeaderFix.Builder

Enclosing class:

SSTableHeaderFix

public static class SSTableHeaderFix.Builder
extends java.lang.Object

Builder to configure and construct an instance of SSTableHeaderFix. Default settings:

• log via the slf4j logger of SSTableHeaderFix
• no dry-run (i.e. validate and fix, if no serious errors are detected)
• no schema callback

If neither withDescriptor(Descriptor) nor withPath(Path) are used, all "live" sstables in all data directories will be scanned.

Method Summary

Modifier and Type	Method and Description
SSTableHeaderFix	build()

SSTableHeaderFix.Builder	error(java.util.function.Consumer<java.lang.String> error)
SSTableHeaderFix.Builder	info(java.util.function.Consumer<java.lang.String> output)
SSTableHeaderFix.Builder	logToList(java.util.List<java.lang.String> output)
SSTableHeaderFix.Builder	schemaCallback(java.util.function.Supplier<java.util.function.Function<Descriptor,TableMetadata>> schemaCallback) Schema callback to retrieve the schema of a table.
SSTableHeaderFix.Builder	warn(java.util.function.Consumer<java.lang.String> warn)
SSTableHeaderFix.Builder	withDescriptor(Descriptor descriptor)
SSTableHeaderFix.Builder	withPath(java.nio.file.Path path) Manually provide an individual sstable or directory containing sstables.

Method Detail

dryRun

public SSTableHeaderFix.Builder dryRun()

Only validate and prepare fix, but do not write updated (fixed) sstable serialization-headers.

info

public SSTableHeaderFix.Builder info(java.util.function.Consumer<java.lang.String> output)

warn

public SSTableHeaderFix.Builder warn(java.util.function.Consumer<java.lang.String> warn)

error

public SSTableHeaderFix.Builder error(java.util.function.Consumer<java.lang.String> error)

withPath

public SSTableHeaderFix.Builder withPath(java.nio.file.Path path)

Manually provide an individual sstable or directory containing sstables. Implementation note: procesing "live" sstables in their data directories as well as sstables in snapshots and backups in the data directories works. But processing sstables that reside somewhere else (i.e. verifying sstables before import) requires the use of withDescriptor(Descriptor).

withDescriptor

public SSTableHeaderFix.Builder withDescriptor(Descriptor descriptor)

schemaCallback

public SSTableHeaderFix.Builder schemaCallback(java.util.function.Supplier<java.util.function.Function<Descriptor,TableMetadata>> schemaCallback)

Schema callback to retrieve the schema of a table. Production code always delegates to the live schema (Schema.instance). Unit tests use this method to feed a custom schema.

build

public SSTableHeaderFix build()

logToList

public SSTableHeaderFix.Builder logToList(java.util.List<java.lang.String> output)
