Record

log_store::kafka::util::record

Struct Record 

Source 
pub(crate) struct Record {
    pub(crate) meta: RecordMeta,
    data: Vec<u8>,
}
Expand description

The minimal storage unit in the Kafka log store.

An entry will be first converted into several Records before producing. If an entry is able to fit into a KafkaRecord, it converts to a single Record. If otherwise an entry cannot fit into a KafkaRecord, it will be split into a collection of Records.

A KafkaRecord is the minimal storage unit used by Kafka client and Kafka server. The Kafka client produces KafkaRecords and consumes KafkaRecords, and Kafka server stores a collection of KafkaRecords.

Fields§

§meta: RecordMeta

The metadata of the record.

§data: Vec<u8>

The payload of the record.

Implementations§

Source§

impl Record

Source

pub(crate) fn try_from_parts( key: Option<&[u8]>, value: Option<Vec<u8>>, ) -> Result<Self>

Decodes a record from the key and value of a [KafkaRecord].

The key is borrowed so that callers can inspect it if decoding fails, e.g. to tell a foreign key apart from a RecordMeta written by an incompatible version of the log store.
