Subject [jira] [Commented] (IGNITE-3592) Provide some kind of pluggable compression SPI support
Date Wed, 12 Jul 2017 21:24:00 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-3592?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16084722#comment-16084722

Amit Pundir commented on IGNITE-3592:

[~vozerov] Compression support for the network messages would be greatly appreciated. Our
cluster is running on clouds on multiple data-centers and we experience significant overhead
in cross data-center calls from Ignite client node to Ignite server node. The round trip time
between the data-centers is still reasonable (under 60 ms).

We are using partitioned cache and our values for the caches are big. Compression for the
network calls will help us a lot. 
Besides that, we have also observed the following operations to take significant amount of
time - 
1. org.apache.ignite.transactions.Transaction ==> commit ==> 2043 milli-seconds
2. org.apache.ignite.spi.communication.tcp.TcpCommunicationSpi ==> createTcpClient ==>
2042 milli-seconds

The above 2 timings suggest significant delay between server node to server node communication
also. Could you please help address these issues sooner than 2.2.

> It may be useful in some cases to compress data stored in cache.
> And in order to give access to compressed data from SQL engine this support should be
implemented in ignite-core level.
