> Snappy compression benefit is lost when generate hash cache RPC
> ---------------------------------------------------------------
>
> Key: PHOENIX-4902
> URL: https://issues.apache.org/jira/browse/PHOENIX-4902
> Project: Phoenix
> Issue Type: Bug
> Reporter: Marcell Ortutay
> Assignee: Marcell Ortutay
> Priority: Minor
>
> Phoenix uses snappy compression on hash caches before it sends them to region
> server:
> {code}
> int maxCompressedSize =
> Snappy.maxCompressedLength(baOut.size());
> byte[] compressed = new byte[maxCompressedSize]; // size for
> worst case
> int compressedSize = Snappy.compress(baOut.getBuffer(), 0,
> baOut.size(), compressed, 0);
> // Last realloc to size of compressed buffer.
> ptr.set(compressed,0,compressedSize);
> {code}
> However, looking at debug output, it seems like the serialized protobuf that
> it sends to region servers does not have the benefits of snappy compression.
> Below is an excerpt of some debug output I put in:
> {code}
> Building an RPC with a cache ptr of size: 39MB // The compressed size is 39MB
> Done serializing the AddServerCacheRequest RPC, size is 206MB // However the
> serialized RPC is 206MB
> And the cache ptr size is: 206MB // And specifically, the byte array that
> contains the serialized hash cache is 206MB
> {code}
> I've made a simple test codebase to attempt to reproduce this bug. It shows
> similar behavior:
> {code}
> bytes size: 10000 bytes
> compressed bytes size: 721 bytes
> message size: 10003 bytes
> compressed message size: 11701 bytes
> {code}
> The code for the simplified example is here:
> https://github.com/ortutay/snappy-bytes-buffer/blob/master/src/main/java/testprotobuf/Main.java
> I observed this behavior in Phoenix 4.14.1
