Levi Tamasi	51b3b7e08c	Remove a now-unnecessary WideColumnSerialization::Serialize variant (#11864) ... Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/11864 Reviewed By: jaykorean Differential Revision: D49445163 fbshipit-source-id: a1275112b9f87a3652df5f155bd215db5819326c	2023-09-20 08:04:35 -07:00
Levi Tamasi	865d5576ad	Support providing the default column separately when serializing columns (#10839) ... Summary: The patch makes it possible to provide the value of the default column separately when calling `WideColumnSerialization::Serialize`. This eliminates the need to construct a new `WideColumns` vector in certain cases (for example, it will come in handy when implementing `Merge`).

Levi Tamasi	24bcab7d5d	Make queries return the value of the default column for wide-column entities (#10483) ... Summary: The patch adds support for wide-column entities to the existing query APIs (`Get`, `MultiGet`, and iterator). Namely, when during a query a wide-column entity is encountered, we will return the value of the default (anonymous) column as the result. Later, we plan to add wide-column specific query APIs which will enable retrieving entire wide-column entities or a subset of their columns.

Levi Tamasi	e9c74bc474	Add wide column serialization primitives (#9915) ... Summary: The patch adds some low-level logic that can be used to serialize/deserialize a sorted vector of wide columns to/from a simple binary searchable string representation. Currently, there is no user-facing API; this will be implemented in subsequent stages.
