Improvement suggested.
Let's say I set the following line:

enter Row struct {
   _msgpack struct{} `msgpack:",asArray"` //nolint: structcheck,unused
   Identifier uint `msgpack:"id"`
   BucketId *uint `msgpack:"bucket_id"`
   Too uint `msgpack:"too"`
   Foo string `msgpack:"foo"`
}

Make an improvement so that you can pass data in this structure in batches, for example to a method

// Row --> batch --> and ..
req := crud.MakeInsertObjectManyRequest("test").Objects(batches[i]) // <-- here

The problem: it is unable to use a batch of tuples as an Objects argument.
The possible solution: Objects should accept interface{} as an arguments instead of []crud.Object.

It was a mistake to use `[]interface{}` or `[]msgpack.CustomEncoder`
as types for an array of tuples and an array of objects. Users were
unable to use slices of custom types as incoming values.

The patch now allows the use of `interface{}` as incoming values. It
makes it easier to use the API, but users need to be more careful.
Therefore, we have also added examples.

You although will need to use MakeInsertManyRequest to insert tuples as arrays, MakeInsertObjectManyRequest for tuples as maps. See new examples from #375 .

Overview

    There are a lot of changes in the new major version. The main ones:

    * The `go_tarantool_call_17` build tag is no longer needed, since
      by default the `CallRequest` is `Call17Request`.
    * The `go_tarantool_msgpack_v5` build tag is no longer needed,
      since only the `msgpack/v5` library is used.
    * The `go_tarantool_ssl_disable` build tag is no longer needed,
      since the connector is no longer depends on `OpenSSL` by default.
      You could use the external library go-tlsdialer[1] to create a
      connection with the `ssl` transport.
    * Required Go version is `1.20` now.
    * The `Connect` function became more flexible. It now allows
      to create a connection with cancellation and a custom `Dialer`
      implementation.
    * It is required to use `Request` implementation types with the
      `Connection.Do` method instead of `Connection.<Request>` methods.
    * The `connection_pool` package renamed to `pool`.

    See the migration guide[2] for more details.

Breaking changes

    connection_pool renamed to pool (#239).

    Use msgpack/v5 instead of msgpack.v2 (#236).

    Call/NewCallRequest = Call17/NewCall17Request (#235).

    Change encoding of the queue.Identify() UUID argument from binary
    blob to plain string. Needed for upgrade to Tarantool 3.0, where a
    binary blob is decoded to a varbinary object (#313).

    Use objects of the Decimal type instead of pointers (#238).

    Use objects of the Datetime type instead of pointers (#238).

    `connection.Connect` no longer return non-working connection
    objects (#136). This function now does not attempt to reconnect
    and tries to establish a connection only once. Function might be
    canceled via context. Context accepted as first argument.
    `pool.Connect` and `pool.Add` now accept context as the first
    argument, which user may cancel in process. If `pool.Connect` is
    canceled in progress, an error will be returned. All created
    connections will be closed.

    `iproto.Feature` type now used instead of `ProtocolFeature` (#337).

    `iproto.IPROTO_FEATURE_` constants now used instead of local
    `Feature` constants for `protocol` (#337).

    Change `crud` operations `Timeout` option type to `crud.OptFloat64`
    instead of `crud.OptUint` (#342).

    Change all `Upsert` and `Update` requests to accept
    `*tarantool.Operations`  as `ops` parameters instead of
    `interface{}` (#348).

    Change `OverrideSchema(*Schema)` to `SetSchema(Schema)` (#7).

    Change values, stored by pointers in the `Schema`, `Space`,
    `Index` structs,  to be stored by their values (#7).

    Make `Dialer` mandatory for creation a single connection (#321).

    Remove `Connection.RemoteAddr()`, `Connection.LocalAddr()`.
    Add `Addr()` function instead (#321).

    Remove `Connection.ClientProtocolInfo`,
    `Connection.ServerProtocolInfo`. Add `ProtocolInfo()` function
    instead, which returns the server protocol info (#321).

    `NewWatcher` checks the actual features of the server, rather
    than relying on the features provided by the user during connection
    creation (#321).

    `pool.NewWatcher` does not create watchers for connections that do
    not support it (#321).

    Rename `pool.GetPoolInfo` to `pool.GetInfo`. Change return type to
    `map[string]ConnectionInfo` (#321).

    `Response` is now an interface (#237).

    All responses are now implementations of the `Response`
    interface (#237). `SelectResponse`, `ExecuteResponse`,
    `PrepareResponse`, `PushResponse` are part of a public API.
    `Pos()`, `MetaData()`, `SQLInfo()` methods created for them to
    get specific info. Special types of responses are used with
    special requests.

    `IsPush()` method is added to the response iterator (#237). It
    returns the information if the current response is a
    `PushResponse`. `PushCode` constant is removed.

    Method `Get` for `Future` now returns response data (#237). To get
    the actual response new `GetResponse` method has been added.
    Methods `AppendPush` and `SetResponse` accept response `Header`
    and data as their arguments.

    `Future` constructors now accept `Request` as their argument
    (#237).

    Operations `Ping`, `Select`, `Insert`, `Replace`, `Delete`,
    `Update`, `Upsert`, `Call`, `Call16`, `Call17`, `Eval`, `Execute`
    of a `Connector` and `Pooler` return response data instead of an
    actual responses (#237).

    `pool.Connect`, `pool.ConnetcWithOpts` and `pool.Add` use a
    new type `pool.Instance` to determinate connection options (#356).

    `pool.Connect`, `pool.ConnectWithOpts` and `pool.Add` add
    connections to the pool even it is unable to connect to it (#372).

    Required Go version from `1.13` to `1.20` (#378).

    multi subpackage is removed (#240).

    Support `IPROTO_FEATURE_SPACE_AND_INDEX_NAMES` for Tarantool
    version >= 3.0.0-alpha1 (#338). It allows to use space and index
    names in requests instead of their IDs.

    `GetSchema` function to get the actual schema (#7).

    Support connection via an existing socket fd (#321).

    `Header` struct for the response header (#237). It can be accessed
    via `Header()` method of the `Response` interface.

   `Response` method added to the `Request` interface (#237).

   New `LogAppendPushFailed` connection log constant (#237).
   It is logged when connection fails to append a push response.

   `ErrorNo` constant that indicates that no error has occurred while
   getting the response (#237).

    Added an ability to mock connections for tests (#237). Added new
    types `MockDoer`, `MockRequest` to `test_helpers`.

    Flaky decimal/TestSelect (#300).

    Tests with crud 1.4.0 (#336).

    Tests with case sensitive SQL (#341).

    Renamed `StrangerResponse` to `MockResponse` (#237).

Other

    All Connection.<Request>, Connection.<Request>Typed and
    Connection.<Request>Async methods are now deprecated. Instead you
    should use requests objects + Connection.Do() (#241).

    All ConnectionPool.<Request>, ConnectionPool.<Request>Typed and
    ConnectionPool.<Request>Async methods are now deprecated. Instead
    you should use requests objects + ConnectionPool.Do() (#241).

Overview

    There are a lot of changes in the new major version. The main ones:

    * The `go_tarantool_call_17` build tag is no longer needed, since
      by default the `CallRequest` is `Call17Request`.
    * The `go_tarantool_msgpack_v5` build tag is no longer needed,
      since only the `msgpack/v5` library is used.
    * The `go_tarantool_ssl_disable` build tag is no longer needed,
      since the connector is no longer depends on `OpenSSL` by default.
      You could use the external library go-tlsdialer[1] to create a
      connection with the `ssl` transport.
    * Required Go version is `1.20` now.
    * The `Connect` function became more flexible. It now allows
      to create a connection with cancellation and a custom `Dialer`
      implementation.
    * It is required to use `Request` implementation types with the
      `Connection.Do` method instead of `Connection.<Request>` methods.
    * The `connection_pool` package renamed to `pool`.

    See the migration guide[2] for more details.

Overview

    There are a lot of changes in the new major version. The main ones:

    * The `go_tarantool_call_17` build tag is no longer needed, since
      by default the `CallRequest` is `Call17Request`.
    * The `go_tarantool_msgpack_v5` build tag is no longer needed,
      since only the `msgpack/v5` library is used.
    * The `go_tarantool_ssl_disable` build tag is no longer needed,
      since the connector is no longer depends on `OpenSSL` by default.
      You could use the external library go-tlsdialer[1] to create a
      connection with the `ssl` transport.
    * Required Go version is `1.20` now.
    * The `Connect` function became more flexible. It now allows
      to create a connection with cancellation and a custom `Dialer`
      implementation.
    * It is required to use `Request` implementation types with the
      `Connection.Do` method instead of `Connection.<Request>` methods.
    * The `connection_pool` package renamed to `pool`.

    See the migration guide[2] for more details.

Breaking changes

    objects (#136). This function now does not attempt to reconnect
    and tries to establish a connection only once. Function might be
    canceled via context. Context accepted as first argument.
    `pool.Connect` and `pool.Add` now accept context as the first
    argument, which user may cancel in process. If `pool.Connect` is
    canceled in progress, an error will be returned. All created
    connections will be closed.

    Add `Addr()` function instead (#321).

    Remove `Connection.ClientProtocolInfo`,
    `Connection.ServerProtocolInfo`. Add `ProtocolInfo()` function
    instead, which returns the server protocol info (#321).

    `NewWatcher` checks the actual features of the server, rather
    than relying on the features provided by the user during connection
    creation (#321).

    interface (#237). `SelectResponse`, `ExecuteResponse`,
    `PrepareResponse`, `PushResponse` are part of a public API.
    `Pos()`, `MetaData()`, `SQLInfo()` methods created for them to
    get specific info. Special types of responses are used with
    special requests.

    `IsPush()` method is added to the response iterator (#237). It
    returns the information if the current response is a
    `PushResponse`. `PushCode` constant is removed.

    Method `Get` for `Future` now returns response data (#237). To get
    the actual response new `GetResponse` method has been added.

    of a `Connector` and `Pooler` return response data instead of an
    actual responses (#237).

    `pool.Connect`, `pool.ConnetcWithOpts` and `pool.Add` use a
    new type `pool.Instance` to determinate connection options (#356).

    `pool.Connect`, `pool.ConnectWithOpts` and `pool.Add` add
    connections to the pool even it is unable to connect to it (#372).

    Required Go version from `1.13` to `1.20` (#378).

    should use requests objects + Connection.Do() (#241).

    All ConnectionPool.<Request>, ConnectionPool.<Request>Typed and
    ConnectionPool.<Request>Async methods are now deprecated. Instead
    you should use requests objects + ConnectionPool.Do() (#241).

Overview

    There are a lot of changes in the new major version. The main ones:

    * The `go_tarantool_call_17` build tag is no longer needed, since
      by default the `CallRequest` is `Call17Request`.
    * The `go_tarantool_msgpack_v5` build tag is no longer needed,
      since only the `msgpack/v5` library is used.
    * The `go_tarantool_ssl_disable` build tag is no longer needed,
      since the connector is no longer depends on `OpenSSL` by default.
      You could use the external library go-tlsdialer[1] to create a
      connection with the `ssl` transport.
    * Required Go version is `1.20` now.
    * The `Connect` function became more flexible. It now allows
      to create a connection with cancellation and a custom `Dialer`
      implementation.
    * It is required to use `Request` implementation types with the
      `Connection.Do` method instead of `Connection.<Request>` methods.
    * The `connection_pool` package renamed to `pool`.

    See the migration guide[2] for more details.

Breaking changes

    connection_pool renamed to pool (#239).

    Use msgpack/v5 instead of msgpack.v2 (#236).

    Call/NewCallRequest = Call17/NewCall17Request (#235).

    Change encoding of the queue.Identify() UUID argument from binary
    blob to plain string. Needed for upgrade to Tarantool 3.0, where a
    binary blob is decoded to a varbinary object (#313).

    Use objects of the Decimal type instead of pointers (#238).

    Use objects of the Datetime type instead of pointers (#238).

    `connection.Connect` no longer return non-working connection
    objects (#136). This function now does not attempt to reconnect
    and tries to establish a connection only once. Function might be
    canceled via context. Context accepted as first argument.
    `pool.Connect` and `pool.Add` now accept context as the first
    argument, which user may cancel in process. If `pool.Connect` is
    canceled in progress, an error will be returned. All created
    connections will be closed.

    `iproto.Feature` type now used instead of `ProtocolFeature` (#337).

    `iproto.IPROTO_FEATURE_` constants now used instead of local
    `Feature` constants for `protocol` (#337).

    Change `crud` operations `Timeout` option type to `crud.OptFloat64`
    instead of `crud.OptUint` (#342).

    Change all `Upsert` and `Update` requests to accept
    `*tarantool.Operations`  as `ops` parameters instead of
    `interface{}` (#348).

    Change `OverrideSchema(*Schema)` to `SetSchema(Schema)` (#7).

    Change values, stored by pointers in the `Schema`, `Space`,
    `Index` structs,  to be stored by their values (#7).

    Make `Dialer` mandatory for creation a single connection (#321).

    Remove `Connection.RemoteAddr()`, `Connection.LocalAddr()`.
    Add `Addr()` function instead (#321).

    Remove `Connection.ClientProtocolInfo`,
    `Connection.ServerProtocolInfo`. Add `ProtocolInfo()` function
    instead, which returns the server protocol info (#321).

    `NewWatcher` checks the actual features of the server, rather
    than relying on the features provided by the user during connection
    creation (#321).

    `pool.NewWatcher` does not create watchers for connections that do
    not support it (#321).

    Rename `pool.GetPoolInfo` to `pool.GetInfo`. Change return type to
    `map[string]ConnectionInfo` (#321).

    `Response` is now an interface (#237).

    All responses are now implementations of the `Response`
    interface (#237). `SelectResponse`, `ExecuteResponse`,
    `PrepareResponse`, `PushResponse` are part of a public API.
    `Pos()`, `MetaData()`, `SQLInfo()` methods created for them to
    get specific info. Special types of responses are used with
    special requests.

    `IsPush()` method is added to the response iterator (#237). It
    returns the information if the current response is a
    `PushResponse`. `PushCode` constant is removed.

    Method `Get` for `Future` now returns response data (#237). To get
    the actual response new `GetResponse` method has been added.
    Methods `AppendPush` and `SetResponse` accept response `Header`
    and data as their arguments.

    `Future` constructors now accept `Request` as their argument
    (#237).

    Operations `Ping`, `Select`, `Insert`, `Replace`, `Delete`,
    `Update`, `Upsert`, `Call`, `Call16`, `Call17`, `Eval`, `Execute`
    of a `Connector` and `Pooler` return response data instead of an
    actual responses (#237).

    `pool.Connect`, `pool.ConnetcWithOpts` and `pool.Add` use a
    new type `pool.Instance` to determinate connection options (#356).

    `pool.Connect`, `pool.ConnectWithOpts` and `pool.Add` add
    connections to the pool even it is unable to connect to it (#372).

    Required Go version from `1.13` to `1.20` (#378).

    multi subpackage is removed (#240).

    msgpack.v2 support is removed (#236).

    pool/RoundRobinStrategy is removed (#158).

    DeadlineIO is removed (#158).

    UUID_extId is removed (#158).

    IPROTO constants are removed (#158).

    Code() method from the Request interface is removed (#158).

    `Schema` field from the `Connection` struct is removed (#7).

    `OkCode` and `PushCode` constants is removed (#237).

    SSL support is removed (#301).

    `Future.Err()` method is removed (#382).

    Support `yield_every` option for crud select requests (#350).

    Support `IPROTO_FEATURE_SPACE_AND_INDEX_NAMES` for Tarantool
    version >= 3.0.0-alpha1 (#338). It allows to use space and index
    names in requests instead of their IDs.

    `GetSchema` function to get the actual schema (#7).

    Support connection via an existing socket fd (#321).

    `Header` struct for the response header (#237). It can be accessed
    via `Header()` method of the `Response` interface.
