Dynohub, a Clojure DynamoDB client with transaction layer https://github.com/ozjongwon/dynohub
Dynohub is a transperent DynamoDB client with a port of transaction library(https://github.com/awslabs/dynamodb-transactions) There are three layers of abstraction: * Dynohub - a plain client layer * Dynolite - a handy client layer on top of Dynohub * Dynotx - a transaction enabled client layer on top of Dynolite (NOTE: All the limits of Amazon's transaction library also applied to Dynohub's transaction layer, Dynotx) Using 'with-transaction' macro you can add transaction! An example (from test): (deftest conflicting-tx-test (testing "Conflicts" (setup-db) (dt/with-transaction [t1] (dt/put-item test-table {:id "conflictingTransactions_Item1" :which-transaction? "t1"}) (dt/put-item test-table {:id "conflictingTransactions_Item2"}) (dt/with-transaction [t2] (dt/put-item test-table {:id "conflictingTransactions_Item1" :which-transaction? "t2 - I win!"}) (utils/ignore-errors (dt/commit t1)) (dt/put-item test-table {:id "conflictingTransactions_Item3"}))) (is (empty? (dl/scan :_tx_table_))) (is (empty? (dl/scan :_image_table_))) (is (empty? (dl/get-item test-table {:id "conflictingTransactions_Item2"}))) (is (not (empty? (dl/get-item test-table {:id "conflictingTransactions_Item3"})))) (is (= (get (dl/get-item test-table {:id "conflictingTransactions_Item1"}) :which-transaction?) "t2 - I win!"))))
