Synopsis

High level interface

getSchema :: forall a. EncodeAvro a => a -> Schema Source #

encodeContainer :: EncodeAvro a => Codec -> Schema -> [[a]] -> IO ByteString Source #

Encode chunks of objects into a container, using 16 random bytes for the synchronization markers. Blocks are compressed (or not) according to the given Codec (nullCodec or deflateCodec).

newSyncBytes :: IO ByteString Source #

Generates a new synchronization marker for encoding Avro containers

encodeContainerWithSync :: EncodeAvro a => Codec -> Schema -> ByteString -> [[a]] -> ByteString Source #

Encode chunks of objects into a container, using the provided ByteString as the synchronization markers.

Packing containers

containerHeaderWithSync :: Codec -> Schema -> ByteString -> Builder Source #

Creates an Avro container header for a given schema.

packContainerBlocks :: Codec -> Schema -> [(Int, ByteString)] -> IO ByteString Source #

Packs a new container from a list of already encoded Avro blocks. Each block is denoted as a pair of a number of objects within that block and the block content.

packContainerBlocksWithSync :: Codec -> Schema -> ByteString -> [(Int, ByteString)] -> ByteString Source #

Packs a new container from a list of already encoded Avro blocks. Each block is denoted as a pair of a number of objects within that block and the block content.

packContainerValues :: Codec -> Schema -> [[ByteString]] -> IO ByteString Source #

Packs a container from a given list of already encoded Avro values Each bytestring should represent exactly one one value serialised to Avro.

packContainerValuesWithSync :: Codec -> Schema -> ByteString -> [[ByteString]] -> ByteString Source #

Packs a container from a given list of already encoded Avro values Each bytestring should represent exactly one one value serialised to Avro.
