Terms in this definition
- ENCODING
A COPY INTO option for CSV sources that states whether the files use UTF8, the default, or UTF16 character encoding.
- LIKE
Compares strings with a pattern that can contain the % and _ wildcards. Because it only understands character patterns, searching big volumes of text this way is much slower than using full-text search.
- JSON
Text-based format for structured data. ARM templates and Cosmos DB documents are written in it, and most Azure REST APIs exchange request and response bodies as application/json.
- Cluster Shared Volumes
Shared failover cluster storage that all nodes write to simultaneously, typically for Scale-Out File Server or Hyper-V. On SAN-backed storage, ReFS-formatted volumes work in redirected mode.
Related terms
- BOM
Bytes placed first in a text file to signal its encoding. Fine-tuning data should be saved as UTF-8 with a BOM, keeping each file below 512 MB; ASCII, UTF-16 or ISO-8859-1 files risk failing validation.
