Field Detail

MAX_MUTATION_SIZE

static final long MAX_MUTATION_SIZE

Method Detail

apply

void apply()

getKeyspaceName

java.lang.String getKeyspaceName()

getTableIds

java.util.Collection<TableId> getTableIds()

key

DecoratedKey key()

getTimeout

long getTimeout(java.util.concurrent.TimeUnit unit)

toString

validateIndexedColumns

default void validateIndexedColumns()

validateSize

void validateSize(int version,
                  int overhead)

Validates size of mutation does not exceed DatabaseDescriptor.getMaxMutationSize().

Parameters:

version - the MessagingService version the mutation is being serialized for. see MessagingService.current_version

overhead - overhadd to add for mutation size to validate. Pass zero if not required but not a negative value.

Throws:

{@link - MutationExceededMaxSizeException} if DatabaseDescriptor.getMaxMutationSize() is exceeded

dataSize

static long dataSize(java.util.Collection<? extends IMutation> mutations)

Computes the total data size of the specified mutations.

Parameters:

mutations - the mutations

Returns:

the total data size of the specified mutations
