as there could be many methods to be executed after transaction, better to do this operation in batches. In order to prevent thousands of promises in parallel that consume more resources that are available

same as in #2582, where runAfterTransactionMethods is a collector of all methods to be executed after transaction is committed. All these methods are executed and only if at least 1 of them fail, an error is thrown.
