Concurrent writes to DynamoDB using transaction api -


we using dynamo db transaction api. in application doing concurrent writes (unique items) dynamo db. following exceptions

com.amazonaws.services.dynamodbv2.model.resourceinuseexception: cannot create preexisting table (service: null; status code: 400; error code: resourceinuseexception; request id: null)

also can batch save when using dynamo db transactions

any inputs helpful.

there's big difference between concurrent createtable calls , put/write calls. you'll error when you're calling createtable when exists.

you need have strict control on how/when create table. once table created, should have no problems doing concurrent writes using of put/write apis.

(keep in mind you'll still 4xx errors if conditional writes , condition fails.)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
