> Key: IGNITE-18584
> URL: https://issues.apache.org/jira/browse/IGNITE-18584
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.14
> Reporter: Ivan Daschinsky
> Priority: Major
> Time Spent: 10m
> Remaining Estimate: 0h
>
> {{org.apache.ignite.internal.processors.compress.CompressionProcessorImpl#compressBuf}}
> is initialized with 1024 extra space, that may be not enough for compressing.
> I.e. snappy requires 2762 extra space for 16K pages.
> The overhead must be calculated during the initialization with help of
> specialized methods, such as
> {{Snappy#maxCompressedLength}}
