Add a function to get the size of a collection/table in bytes.

[faisalill]

What's Changed:

Added getCollectionSize method to MariaDB, MySQL, SQLite and MongoDB adapters.
The function for Postgres is working but it is giving an error during test so I just commented the code out.

Tests:

I have checked manually using the getCollectionSize method it worked.
I did add a test to check whether it returns a string.

Great start 😁

@abnegate ,

1.Fixed the stuff u mentioned.

2.As for the testing part I don't know why but it keeps returning me 0 (checked both before and after adding data) . That's the reason I used assertIsInt. Postgres is giving me the collection size in bytes but during test it is giving me an error SQLite too but it's related to the function returning null/0 as I said.

3. Regarding the Documentation, I guess only Document and Relationship methods are pending.

4. Can I get permission to add try catch blocks which throws Database Exception as there are a lot of methods in the adapters that are missing it.

Thank you for your time.

1. Fixed the stuff u mentioned.

Awesome, nice work!

2. For the testing part I don't know why but it keeps returning me 0 (checked both before and after adding data) . That's the reason I used assertIsInt. Postgres is giving me the collection size in bytes but during test it is giving me an error SQLite too but it's related to the function returning null/0 as I said.

Please try to dig into this further, we'll need to get all adapters working. How are you running the tests? The Postgres issue is strange for the test suite. For the SQLite issue, try some extra debugging, adding var_dump or other logging to see what the function is doing at each step, that should help figure out why you're getting null.

3. Regarding the Documentation, I guess only Document and Relationship methods are pending.

Awesome, let's add those methods too

4. Can I get permission to add try catch blocks which throws Database Exception as there are a lot of methods in the adapters that are missing it.

Let's address that seperately, it's outside the scope of this PR. Make sure you've merge in the upstream main branch too, a lot of the Exception's have been updated to DatabaseException. DM me if you need help with it

@abnegate,

1. Completed the documentation will create a new PR for it.
2. Got the tests working.
3. Changed the tests. (I check whether the size before and after data is greater)
   Thank you

@abnegate,

1. Formatted using composer format for indentation.
2. Changed the amount of attributes created for testing.
3. Regarding test for mysql : I tried to add different attributes and almost 10000 documents but still mysql keeps returning me 65536 as the size. I checked the size using sql terminal and it still returns me 65536. Adding so many documents is just increasing the time of tests. Rest all the adapters are working fine their size changes but mysql.

[abnegate]

Let's fix the indentation here

[faisalill]

@abnegate,
1, Fixed the indentation, and other stuff you mentioned.
2. I tried to add different documents in huge quantity (20000 docs), tried the sql terminal to insert and check the size and still it is returning 65536.

[faisalill]

@abnegate ,
Fixed the indentation as you mentioned.

[faisalill]

@abnegate ,
The tests are working fine now.
Can you re-review please

[faisalill]

@abnegate Made the changes

I think we missed the full-text index calculations table size? since there are additional tables.
cc @abnegate

[fogelito]

looks like the first FT will create 6 table:
6 table:
appwrite/fts_00000000000004a9_00000000000001ca_index_1
appwrite/fts_00000000000004a9_00000000000001ca_index_2
appwrite/fts_00000000000004a9_00000000000001ca_index_3
appwrite/fts_00000000000004a9_00000000000001ca_index_4
appwrite/fts_00000000000004a9_00000000000001ca_index_5
appwrite/fts_00000000000004a9_00000000000001ca_index_6

with 5 additional table:

appwrite/fts_00000000000004a9_deleted_cache
appwrite/fts_00000000000004a9_deleted
appwrite/fts_00000000000004a9_config
appwrite/fts_00000000000004a9_being_deleted_cache
appwrite/fts_00000000000004a9_being_deleted

The second fulltext index for the same table will create only 6 tables

[abnegate]

@fogelito Any ideas how we can count those too?

[abnegate]

@faisalill Please add another test that:

1. Creates a collection
2. Creates some documents
3. Gets the size
4. Adds a fulltext index to the collection
5. Checks that the size is larger than before

[faisalill]

@abnegate
Added test for full text indexing it worked for all adapters except for mongoDB.
MongoDB is returning the same size before and after creating an index.
Will try to work on it and update u on the same.

[faisalill]

@abnegate@fogelito
Size increases when full text index is added.
Added tests for it too.
