kandi X-RAY | athena Summary

athena is a Python library typically used in Artificial Intelligence, Speech, Deep Learning, Pytorch, Tensorflow, Transformer applications. athena has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

Athena is an open-source implementation of end-to-end Automatic Speech Recognition (ASR) engine. Currently this project supports training and decoding of Connectionist Temporal Classification (CTC) based model, transformer-basesd encoder-decoder model and Hybrid CTC/attention based model, and MPC based unsupervised pretraning. Our vision is to empower both industrial application and academic research on end-to-end models for speech recognition. To make ASR accessible to everyone, we're also releasing some example implementation based on some opensource dataset, like HKSUT, Librispeech. All of our models are implemented in Tensorflow>=2.0.3.

            Can you have a schema or folder structure in AWS Athena?
            Asked 2022-Mar-29 at 10:17

            I am copying an entire snowflake DB into S3 to be viewed through Athena. I would like to preserve the schema/hierarchy so that the corresponding queries do not change. All the files are organized properly for this in S3 as follows

            DataBase/Schema/Folder/Table/{parquet files}

            When I crawl with Glue they all end up in one DB at the same level. Is it possible to have a similar folder structure in Athena?

            Right now all queries in Athena are like

            The only logical grouping of tables available in Athena is a database, and as you have indicated, there is no concept of hierarchy, schemas, or folders in Athena.

            Database and schema comprise a namespace in Snowflake. If your intention is to simply have a similar namespace, what you can do is combine the Snowflake database d1 and schema name s1 to create a flattened logical grouping in Athena d1_s1. Then you can do:

            Correct Method to Delete Delta Lake Partion on AWS s3
            Asked 2022-Mar-10 at 15:34

            I need to delete a Delta Lake partition with associated AWS s3 files and then need to make sure AWS Athena displays this change. The purpose is because I need to rerun some code to re-populate the data.

            I tried this

            ANSWER

            Answered 2022-Mar-05 at 14:11

            Although you performed delete operation, data is still there because Delta tables have history, and actual deletion of the data will happen only when you execute VACUUM operation and operation time will be older than default retention period (7 days). If you want to remove data faster, then you can run VACUUM command with parameter RETAIN XXX HOURS, but this may require setting some additional properties to enforce that - refer documentation for more details.

            Out of the box, you can have QueryPlanningTime, QueryQueuetime etc. metrics. Nonetheless, you need Cloudtrail to track who executed.

            Asked 2022-Feb-18 at 19:11

            I have a Glue table on S3 where partitions are populated through Spark save mode overwrite (script executed through Glue job).

            What is expected behavior from Athena if we are querying such partitions while they are being overwritten?

            ANSWER

            Answered 2022-Feb-17 at 07:52

            New partitions are being picked up by Athena as long as you set enableUpdateCatalog = True when writing. If you just overwrite the content of existing partitions, Athena will be able to query the data, as long as you don't have a schema mismatch.

            If you switch to the OpenX SerDe, you can create a SerDe mapping for JSON fields with special characters like $ in the name.

            You appear to be confusing conditions within an ON with conditions in a WHERE.

            Your left join query returned rows where aw had other values because you were providing conditions for how to join the rows between tables. It does not limit the rows from the 'left' table.

            If you only want to return rows where the LEFT table (aw) date matches 2022-02-05, then you should put those conditions in a WHERE:
