问题
I'm using Athena Query Execution to retrieve data from a Glue Table. A Crawler updates this table every hour using a S3 Bucket which is continuously updated by Kinesis Firehose.
My Node.js server executes basic queries using Athena. But I realized that some of the requests takes so long that my server throws Server Request Timeout.
I checked the Query History in Athena and I saw some of the latest requests' state is Queued which means they are waiting to be executed. They all have a small Run Time in the range of 1 to 5 seconds. It's obvious that the problem is not the Run Time causes timeouts but it's the queue.
How can I speed up the execution of these queries? or how can I increase concurrent execution limits so Athena immediately executes them?
