It has BLOB columns that contain video thumbnails in JPG format (around 100-500KB per row). I've registered an output formatter that extends `datasette.blob_renderer.render_blob` function and serves the column with `image/jpeg` content type. ```python from datasette.blob_renderer import render_blob async def render_jpg(datasette, database, rows, columns, request, table, view_name): response = await render_blob(datasette, database, rows, columns, request, table, view_name) response.content_type = ""image/jpeg"" response.headers[""Content-Disposition""] = f'inline; filename=""image.jpg""' return response @hookimpl def register_output_renderer(): return { ""extension"": ""jpg"", ""render"": render_jpg, ""can_render"": lambda: True, } ``` This works well. I can visit `http://localhost:8001/mydb/videos/1.jpg?_blob_column=thumbnail` and view the image. I want to display the image directly with an `` tag (lazy-loaded of course). So, I need a URL, because embedding base64 would increase the page size too much (each image > 100KB). Datasette generates a link with `.blob` extension for blob columns. It does this by calling `datasette.urls.row_blob` https://github.com/simonw/datasette/blob/7a2ed9f8a119e220b66d67c7b9e07cbab47b1196/datasette/views/table.py#L169-L179 But I have no way of getting the row inside the `render_cell` hook. ```python @hookimpl def render_cell(value, column, table, database, datasette): if isinstance(value, bytes) and imghdr.what(None, value): # generate url return '$renderedLink' ``` Any pointers?",107914493,issue,,,"{""url"": ""https://api.github.com/repos/simonw/datasette/issues/1300/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed 642572841,MDU6SXNzdWU2NDI1NzI4NDE=,859,Database page loads too slowly with many large tables (due to table counts),3243482,open,0,,,21,2020-06-21T14:23:17Z,2021-08-25T21:59:55Z,,CONTRIBUTOR,,"Hey, I have a database that I save in HTML from couple of web scrapers. There are around 200k+, 50+ rows in a couple of tables, with sqlite file weighing around 600MB. The app runs on a VPS with 2 core CPU, 4GB RAM and refreshing database page regularly takes more than 10 seconds. I was suspecting that counting tables was the culprit, but manually running `select count(*) from table_name` for the largest table finishes under a second. I've looked at the source code. There's a check for index page for mutable databases larger than 100MB https://github.com/simonw/datasette/blob/799c5d53570d773203527f19530cf772dc2eeb24/datasette/views/index.py#L15 but this check is not performed for database page. I've manually crippled `Database::table_counts` method ```py async def table_counts(self, limit=10): if not self.is_mutable and self.cached_table_counts is not None: return self.cached_table_counts # Try to get counts for each table, $limit timeout for each count counts = {} for table in await self.table_names(): try: # table_count = ( # await self.execute( # ""select count(*) from [{}]"".format(table), # custom_time_limit=limit, # ) # ).rows[0][0] counts[table] = 10 # table_count # In some cases I saw ""SQL Logic Error"" here in addition to # QueryInterrupted - so we catch that too: except (QueryInterrupted, sqlite3.OperationalError, sqlite3.DatabaseError): counts[table] = None if not self.is_mutable: self.cached_table_counts = counts return counts ``` now the page loads in <100ms. Is it possible to apply size check on database page too?
