avro_codecrejecteddeflateand the OCF reader's codec whitelist did too, so atable whose schema carries
manifest.compression=deflatecould be neitherwritten nor read: every scan failed with
avro ocf: unsupported codec: deflate.The option comes from the persisted schema, so a table created by Java brings it
along to every paimon-rust process. Java accepts deflate through
CodecFactory.fromString.Read support is a regression:
553e4a3(#281) advertised "snappy/deflate/zstd"in its own message while shipping only three arms, replacing a reader that did
handle deflate. Write support is parity work. At HEAD the crate already reads
deflate-compressed Avro data files, so only manifests were refused.
No upstream report; found by inspection.
bzip2andxzare the same gap andstay rejected. Drive-by: the snappy mismatch message said CRC32C where the code
computes CRC-32.
