Fields

partitions_count: i32

How many partitions in topic. Must less than database limit. Default limit - 10.

retention_period_ms: i64

How long data in partition should be stored. Must be greater than 0 and less than limit for this database. Default limit - 36 hours.

message_group_seqno_retention_period_ms: i64

How long last written seqno for message group should be stored. Must be greater then retention_period_ms and less then limit for this database. Default limit - 16 days.

max_partition_message_groups_seqno_stored: i64

How many last written seqno for various message groups should be stored per partition. Must be less than limit for this database. Default limit - 6*10^6 values.

supported_format: i32

Max format version that is allowed for writers. Must be value from enum FormatVersion. Writes with greater format version are forbiden.

supported_codecs: Vec<i32>

List of allowed codecs for writers. Writes with codec not from this list are forbiden.

max_partition_storage_size: i64

Max storage usage for each topic’s partition. Must be less than database limit. Default limit - 130 GB.

max_partition_write_speed: i64

Partition write speed in bytes per second. Must be less than database limit. Default limit - 1 MB/s.

max_partition_write_burst: i64

Burst size for write in partition, in bytes. Must be less than database limit. Default limit - 1 MB.

client_write_disabled: bool

Disallows client writes. Used for mirrored topics in federation.

read_rules: Vec<ReadRule>

List of consumer read rules for this topic.

attributes: HashMap<String, String>

User and server attributes of topic. Server attributes starts from “_” and will be validated by server.

remote_mirror_rule: Option<RemoteMirrorRule>

remote mirror rule for this topic.

Implementations

impl TopicSettings

pub fn supported_format(&self) -> Format

Returns the enum value of supported_format, or the default if the field is set to an invalid enum value.

pub fn set_supported_format(&mut self, value: Format)

Sets supported_format to the provided enum value.

pub fn supported_codecs(
    &self
) -> FilterMap<Cloned<Iter<'_, i32>>, fn(_: i32) -> Option<Codec>>

Returns an iterator which yields the valid enum values contained in supported_codecs.

pub fn push_supported_codecs(&mut self, value: Codec)

Appends the provided enum value to supported_codecs.
