### Connect, Create Schema/Table, and Insert Data with VastDB SDK

Source: https://vast-data.github.io/data-platform-field-docs/_sources/vast_vectordb/quickstart.ipynb

Connect to VastDB, create or get a schema and table, and insert data using the SDK. This example includes print statements for tracking the process. Ensure all necessary variables are defined.

```python
import vastdb
import pyarrow as pa
import datetime as dt

# --- Assume these variables are defined ---
# VASTDB_ENDPOINT = "your_endpoint_url"
# AWS_ACCESS_KEY_ID = "your_access_key"
# AWS_SECRET_ACCESS_KEY = "your_secret_key"
# BUCKET_NAME = "cneundorf-db"
# SCHEMA_NAME = "test"
# TABLE_NAME = "vectors_101"
# ------------------------------------------

session = vastdb.connect(
    endpoint=VASTDB_ENDPOINT,
    access=AWS_ACCESS_KEY_ID,
    secret=AWS_SECRET_ACCESS_KEY
)

print("Connecting to VAST...")
with session.transaction() as tx:
    print(f"Starting transaction {tx.txid}...")
    bucket = tx.bucket(BUCKET_NAME)
    
    # Get or create the schema
    schema = bucket.schema(SCHEMA_NAME, fail_if_missing=False) or bucket.create_schema(SCHEMA_NAME)
    print(f"Using schema: {SCHEMA_NAME}")

    # Define the table structure
    dimension = 5
    columns = pa.schema([
        ("id", pa.int64()),
        ("vec", pa.list_(pa.field(name="item", type=pa.float32(), nullable=False), dimension)),
        ('vec_timestamp', pa.timestamp('us'))
    ])

    # Get or create the table
    table = schema.table(TABLE_NAME, fail_if_missing=False) or schema.create_table(TABLE_NAME, columns)
    
    print(f"Using table: {TABLE_NAME}")

    # Insert a few rows of data.
    arrow_table = pa.table(schema=columns, data=[
        [1, 2, 3],
        [[1.0, 2.0, 3.0, 4.0, 5.0], [6.0, 7.0, 8.0, 9.0, 10.0], [11.0, 12.0, 13.0, 14.0, 15.0]],
        [dt.datetime(2024, 4, 10, 12, 34),
         dt.datetime(2024, 4, 11, 12, 34),
         dt.datetime(2024, 4, 13, 12, 34)]
    ])


    # The transaction is automatically committed when exiting the context
    print("Inserting data...")
    table.insert(arrow_table)
    print("Data inserted.")

print("Transaction committed.")
```

### Install required packages

Source: https://vast-data.github.io/data-platform-field-docs/_sources/vast_database/query/ray_daft_vastdb.ipynb

Install Ray, Daft, and the VAST DB client library.

### Set up NiFi 2.x with VastDB using Docker

Source: https://vast-data.github.io/data-platform-field-docs/vast_datastore/nifi/quickstart.html

This script sets up a local environment for running NiFi 2.x with VastDB extensions using Docker. It downloads the latest VastDB NiFi processor and other necessary extensions, then starts a NiFi container. Ensure the NIFI_HOST variable is correctly set for your environment. This setup is experimental and not recommended for production.

```bash
# set this to the hostname or ip address where you are running NiFi
export NIFI_HOST=hostname_or_ipaddress

if [[ "$NIFI_HOST" == "hostname_or_ipaddress" ]]; then
    echo "ERROR: NIFI_HOST variable MUST be set for your environment."
    exit 1
fi

### Snapshot Path Example

Source: https://vast-data.github.io/data-platform-field-docs/vast_catalog/python-sdk-vast-catalog.html

This example shows the typical naming convention for catalog snapshot paths within a bucket. These paths are used to access historical data versions.

### Configure VastDB Environment

Source: https://vast-data.github.io/data-platform-field-docs/_sources/vast_database/ingestion/python_sdk_grib2_import.ipynb

Setup environment variables for VastDB connection parameters.

```python
import os

VASTDB_ENDPOINT = os.getenv("VASTDB_ENDPOINT")
VASTDB_ACCESS_KEY = os.getenv("VASTDB_ACCESS_KEY")
VASTDB_SECRET_KEY = os.getenv("VASTDB_SECRET_KEY")

# Use NYT BUCKET (DB) for now
VASTDB_NYT_BUCKET=os.getenv("VASTDB_NYT_BUCKET")
schema_name = 'grib2'
table_name = 'grib2'
```

--------------------------------

### Start Spark Session

Source: https://vast-data.github.io/data-platform-field-docs/_sources/vast_database/tuning/Spark_Predicate_Pushdown.ipynb

Initializes a Spark session with configurations for Vast DB and Iceberg catalogs.

```python
import socket
import os
import pyspark
from pyspark.conf import SparkConf
from pyspark.sql import SparkSession
import pandas as pd
pd.set_option("max_colwidth", 150)

conf = SparkConf()
conf.setAll([
    ("spark.driver.host", socket.gethostbyname(socket.gethostname())),
    ("spark.sql.execution.arrow.pyspark.enabled", "false"),
     # VASTDB
    ("spark.sql.catalog.ndb", 'spark.sql.catalog.ndb.VastCatalog'),

### Consume Kafka Topics by Prefix

Source: https://vast-data.github.io/data-platform-field-docs/_sources/vast_kafka/utils.md

Consume messages from all topics that start with a specific prefix. This example consumes from topics starting with 'prod-'.

```bash
VAST_BROKER=172.200.204.1:9092

# Example: Consume from all topics starting with 'prod-'
docker run --rm jforge/kafka-tools kafka-console-consumer.sh \
    --bootstrap-server $VAST_BROKER \
    --whitelist 'prod-*' \
    --from-beginning

### Get Min/Max and Max Rows

Source: https://vast-data.github.io/data-platform-field-docs/vast_database/ingestion/python_sdk_netcdf_import.html

Analyzes a specified column in a Vast-Data table to find its minimum and maximum values, and retrieves the row(s) containing the maximum value. Requires `ibis-framework` to be installed for fetching max rows.

### Define base_setup function

Source: https://vast-data.github.io/data-platform-field-docs/_sources/vast_database/admin/vastdb_py_setup.ipynb

Configures a Vast Database by creating a VIP pool, user, S3 access keys, view, and schema.

```python
from vastpy import VASTClient

    client = VASTClient(user=username, password=password, address=address)

    database_owner = config['user']['name']

    try:

### Setup Dremio Docker Environment

Source: https://vast-data.github.io/data-platform-field-docs/vast_database/query/dremio_quickstart/howto.html

Creates a directory, downloads the Dremio connector JAR, and defines a Dockerfile for building a Dremio image with Vast Data connector support. Ensure the placeholder URL for the JAR is replaced with a public URL.

```bash
mkdir dremio_docker
cd dremio_docker

# TODO: replace this with public URL
wget https://artifactory.vastdata.com/ui/repos/tree/General/vast-custom/tabular/connectors/dre[%E2%80%A6]3/20240901/dremio-vast-data-connector-3.0.3-SNAPSHOT.jar
