>
> Every time we call {{ProtobufLogReader#readNext}} we consume the input stream
> associated to the {{FSDataInputStream}} from the WAL that we are reading.
> Under certain conditions, e.g. when using the encryption at rest
> ({{CryptoInputStream}}) the stream can return partial data which can cause a
> premature EOF that cause {{inputStream.getPos()}} to return to the same
> origina position causing {{ProtobufLogReader#readNext}} to re-try over the
> reads until the WAL is rolled.
> The side effect of this issue is that {{ReplicationSource}} can get stuck
> until the WAL is rolled and causing replication delays up to an hour in some
> cases.
