Igor Sapego commented on IGNITE-5097: ------------------------------------- So, the max size is going to take 5 bytes then? In that case, in platforms we'd need to reserve 5 bytes, which going to INCREASE collections/arrays size for platforms. So, while we optimizing collections size for Java, we are going to make it larger and slower for [de]serialization for platforms. I can't say I like the thought. > BinaryMarshaller should write ints in "varint" encoding where it makes sense > ---------------------------------------------------------------------------- > > Key: IGNITE-5097 > URL: https://issues.apache.org/jira/browse/IGNITE-5097 > Project: Ignite > Issue Type: Task > Components: general > Affects Versions: 2.0 > Reporter: Vladimir Ozerov > Assignee: Vyacheslav Daradur > Labels: important, performance > Fix For: 2.1 > > > There are a lot of places in the code where we write integers for some > special purposes. Quite often their value will be vary small, so that > applying "varint" format could save a lot of space at the cost of very low > additional CPU overhead. > Specifically: > 1) Array/collection/map lengths > 2) BigDecimal's (usually will save ~6 bytes) > 3) Strings > 4) Enum ordinals -- This message was sent by Atlassian JIRA (v6.3.15#6346)
