> Key: IGNITE-8039
> URL: https://issues.apache.org/jira/browse/IGNITE-8039
> Project: Ignite
> Issue Type: Improvement
> Components: documentation, thin client
>Affects Versions: 2.4
>Reporter: Alexey Kosenchuk
>Assignee: Prachi Garg
>Priority: Major
> Fix For: 2.5
>
>
> Assuming the Binary Client Protocol spec should be detalized enough to allow
> a client development basing on the spec only, w/o looking at other client
> implementations and asking additional questions...
> The following should be clarified / corrected in the Binary Client Protocol
> spec (v.2.4)
> (https://apacheignite.readme.io/v2.4/docs/binary-client-protocol#section-data-format):
> Type Codes table:
> -
> - UUID (Guid) size: should be 16 bytes, not 8 (?)
> - what is Object array (type code 23) ? What is the difference between it and
> Objects Wrapped In Array (type code 27) ?
> - what is Collection USER_SET ?
> - what is Collection USER_COL ?
> - what is Collection SINGLETON_LIST ?
> - Collection: misprint: should be "... + length ..."
> - what is Decimal ?
> - what is Timestamp ?
> - what is Time ?
> Complex Objects:
>
> - what does flag USER_TYPE mean ?
> - Schema "field Id; Java-style hash code of field" -> should be "... of field
> name".
> - "Repeat for as many times as the total number of schemas you have" ->
> should be "... total number of fields you have".
> - is it mandated that the number of fields in the Schema must be equal to the
> number of fields in the Data Object ?
> Objects Wrapped In Array
>
> - may binary objects with different type codes be in the same array ?
> - may complex objects with different type ids be in the same array ?
> - "All cache operations return complex objects inside a wrapper (but not
> primitives)." -> does it mean that in general a complex object (103) must
> always be sent via the Binary Protocol in a wrapper (27)?
> - "Byte array size" -> "Payload size" or "Size of the whole array with
> header" ?
> - Offset. What is "object graph" here ? The Binary Protocol nowhere describes
> any relations ("graph") between data objects in the protocol.
> Terminology
> ---
> Not critical but would be really convenient to define and use the same terms
> along the whole spec. For example:
> - "binary object" is always the same as "data object" of any type (?). Can be
> "standard/predefined type object" or "complex object".
> - "cluster" or "server" ?
> - "cluster member" or "server nodes" ?
