Struct aws_sdk_kinesis::model::PutRecordsRequestEntry

#[non_exhaustive]
pub struct PutRecordsRequestEntry {
    pub data: Option<Blob>,
    pub explicit_hash_key: Option<String>,
    pub partition_key: Option<String>,
}

Represents the output for PutRecords.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

data: Option<Blob>

The data blob to put into the record, which is base64-encoded when the blob is serialized. When the data blob (the payload before base64-encoding) is added to the partition key size, the total size must not exceed the maximum record size (1 MiB).

explicit_hash_key: Option<String>

The hash value used to determine explicitly the shard that the data record is assigned to by overriding the partition key hash.

partition_key: Option<String>

Determines which shard in the stream the data record is assigned to. Partition keys are Unicode strings with a maximum length limit of 256 characters for each key. Amazon Kinesis Data Streams uses the partition key as input to a hash function that maps the partition key and associated data to a specific shard. Specifically, an MD5 hash function is used to map partition keys to 128-bit integer values and to map associated data records to shards. As a result of this hashing mechanism, all data records with the same partition key map to the same shard within the stream.

Implementations

impl PutRecordsRequestEntry

pub fn data(&self) -> Option<&Blob>

The data blob to put into the record, which is base64-encoded when the blob is serialized. When the data blob (the payload before base64-encoding) is added to the partition key size, the total size must not exceed the maximum record size (1 MiB).

pub fn explicit_hash_key(&self) -> Option<&str>

The hash value used to determine explicitly the shard that the data record is assigned to by overriding the partition key hash.

pub fn partition_key(&self) -> Option<&str>

Determines which shard in the stream the data record is assigned to. Partition keys are Unicode strings with a maximum length limit of 256 characters for each key. Amazon Kinesis Data Streams uses the partition key as input to a hash function that maps the partition key and associated data to a specific shard. Specifically, an MD5 hash function is used to map partition keys to 128-bit integer values and to map associated data records to shards. As a result of this hashing mechanism, all data records with the same partition key map to the same shard within the stream.
