kandi X-RAY | athena Summary
Athena is an open-source implementation of end-to-end speech processing engine. Our vision is to empower both industrial application and academic research on end-to-end models for speech processing. To make speech processing available to everyone, we're also releasing example implementation and recipe on some opensource dataset for various tasks (Automatic Speech Recognition, Speech Synthesis, Voice Conversion, Speaker Recognition, etc). All of our models are implemented in Tensorflow>=2.0.1. For ease of use, we provide Kaldi-free pythonic feature extractor with Athena_transform.

QUESTION
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
...ANSWER
Answered 2022-Mar-29 at 10:17The 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:
QUESTION
I am querying an S3 using Athena and I want to select the key until certain path level. Here are some key examples:
- project=proj1/ID=SS02769/input=client1/version=X3900/data/fold1/file1.csv
- project=proj1/ID=SS02770/input=client1/version=X4500/data/fold1/file2.csv
- project=proj1/ID=SS02775/input=client1/version=X9000/data/fold1/file3.csv
I want to query these rows and select all the string until 'data/' is there any regex expression to use or any sql expression? Actually I tried the next regex expression but does not work :

QUESTION
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 14:11Although 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.

I am trying to concatenate multiple tables then save it with partitoned key.

QUESTION
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 07:52New 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.
QUESTION
I'm new to athena even though I have some short experience with Hive.
I'm trying to create a table from JSON files, which are exports from MongoDB. My problem is that MongoDB uses $oid, $numberInt, $numberDoble and others as internal references, but '$' is not accepted in a column name in Athena.
This is a one line JSON file that I created to test:
...ANSWER
Answered 2022-Feb-17 at 13:43If you switch to the OpenX SerDe, you can create a SerDe mapping for JSON fields with special characters like $ in the name.
See AWS Blog entry Create Tables in Amazon Athena from Nested JSON and Mappings Using JSONSerDe , section "Walkthrough: Handling forbidden characters with mappings".
A mapping that would work for your example:
QUESTION
I am trying to run query on Athena which is not behaving as expected:
...ANSWER
Answered 2022-Feb-15 at 04:25You 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:

I am getting below error when i am trying to create New Dataset in Quicksight from Athena. I tried for "Table" and "view". It gives below error :
...ANSWER
Answered 2021-Nov-14 at 07:23You can fix this by adding S3 bucket permission in the QuickSight console.
Go to:
Manage QuickSight -> Security & permissions -> Add or remove -> In S3 -> Details -> Select the bucket you want to query -> Update

Install athena
These packages are usually required for ASR tasks, we assume they have been installed when running the recipe for ASR tasks. You can find installation scripts of them in tools/.
For multiple GPU/CPU training You have to install the horovod, you can find out more information from the horovod website.
For WFST decoding You have to install pydecoder, installation guide for pydecoder can be found athena-decoder website.
Once athena is successfully installed, you should do source tools/env.sh firstly before doing other things.
For installing some other supporting tools, you can check the tools/install*.sh to install kenlm, sph2pipe, spm and ... [Optional]
