box.session.push is deprecated starting from Tarantool 3.0. We're going to disable it in Tarantool 4.0 with the ability to enable it via the compat.box_session_push_deprecation option. In Tarantool 5.0 we're going to drop it completely. See tarantool/tarantool#8802.

Tarantool integration CI reports a failure if box.session.push is disabled by setting compat.box_session_push_deprecation to 'new'. Please remove all usages of box.session.push from this project code.

@locker @unera do you want to completely remove the feature from the connector or leave a user the ability to use the feature for Tarantool < 5.0?

We want to make a next major release of the connector soon, so we can don't worry about a backward compatibility here from our side.

According to @unera, the box.session.push feature is dangerous so it should be dropped completely.

Too bad. Box.watch() is not an alternative when we use C connector

We have a mechanism, that can not be repaired (without protocol refactoring).

  • It has a broken design of API (should be connected to request, but connected to session)
  • It has a problem with OOM-killer (now server-side)
  • If IPROTO protocol doesn't change, we can only move OOM problems from server-side to client-side.

More details are described by @locker, here

PS: I looked through the tarantool-centrifuge code. It uses session.push as a data stream, so it is an example of OOM problem. If tarantool has too many slow clients, it can be killed by OOM.

Yes, watch provides only state events, but now tarantool has no unbroken stream mechanisms.

It's a shame but we want to avoid new users at the broken feature.
We have a plan to provide a new data-stream mechanism.

Hello, killed by OOM due to unbounded buffer growth right? it's possible to add limits (on application level or Tarantool level probably) I suppose to drop slow connections or drop messages. We were planning to do this at some point. I suppose any alternative streaming mechanism will have similar trade-offs in terms of limits to prevent OOM due to slow connections?

I'd also like to mention the real-life use case of box.session.push we have - https://centrifugal.dev/blog/2023/08/29/using-centrifugo-in-rabbitx. Nine months in production with zero issues. So I'd like to ask once again - please do not remove the feature without attempt to improve it (which seems possible), maybe properly document it, or providing a good alternative to it. We can replace push with polling - but it will introduce unnecessary latencies.

Any solution is a trade-off, if box.session.push does not introduce global problems for Tarantool protocol/architecture - it has its use cases. Redis PUB/SUB is widely used - it's built on the same principles I believe and nobody want it to be removed.

it's possible to add limits

Sorry, but it isn't possible. We analysed the problem and found that it's impossible without protocol modifications. The problem can be moved from server to client, but can not be solved.

I checked the code. You have polling variant, so it wouldn't heavy to use WATCH variant.

PS: zero issues - because You have too many megabytes of RAM and too small slow clients.

Thanks for your answer!

Is it possible to read the analysis somewhere? It's not clear what is the actual problem and why it can't be solved by introducing limits. As I showed there are uses cases where pushing to session seems totally valid. I suppose a wise planning given the number of conns, data size, etc and considering RAM limits on the machine is also a concern for general Tarantool spaces, not sure why RAM spent on box.session.push is special.

I checked the code. You have polling variant, so it wouldn't heavy to use WATCH variant.

What does it mean to use WATCH? Could you show some example? From what I've seen watch is delivering only the latest message, so if the idea is to load messages upon notification - then I suppose the buffer on Tarantool side should be still limited somehow, and we get the same problem. And increased latency.

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.

    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

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.

    * 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

    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).

    `map[string]ConnectionInfo` (#321).

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

    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.

    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).

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.

   `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).
