what will be great if signoz support databend, reference as: https://github.com/datafuselabs/databend

No, signoz doesn't support databend and principally the reason is the DDL statements used in the clickhouse setup aren't parseable by Databend, for example:

CREATE TABLE IF NOT EXISTS signoz_index (
  timestamp DateTime64(9) CODEC(Delta, ZSTD(1)),
  traceID String CODEC(ZSTD(1)),
  spanID String CODEC(ZSTD(1)),
  parentSpanID String CODEC(ZSTD(1)),
  serviceName LowCardinality(String) CODEC(ZSTD(1)),
  name LowCardinality(String) CODEC(ZSTD(1)),
  kind Int32 CODEC(ZSTD(1)),
  durationNano UInt64 CODEC(ZSTD(1)),
  tags Array(String) CODEC(ZSTD(1)),
  tagsKeys Array(String) CODEC(ZSTD(1)),
  tagsValues Array(String) CODEC(ZSTD(1)),
  statusCode Int64 CODEC(ZSTD(1)),
  references String CODEC(ZSTD(1)),
  externalHttpMethod Nullable(String) CODEC(ZSTD(1)),
  externalHttpUrl Nullable(String) CODEC(ZSTD(1)),
  component Nullable(String) CODEC(ZSTD(1)),
  dbSystem Nullable(String) CODEC(ZSTD(1)),
  dbName Nullable(String) CODEC(ZSTD(1)),
  dbOperation Nullable(String) CODEC(ZSTD(1)),
  peerService Nullable(String) CODEC(ZSTD(1)),

  INDEX idx_tagsKeys tagsKeys TYPE bloom_filter(0.01) GRANULARITY 64,
  INDEX idx_tagsValues tagsValues TYPE bloom_filter(0.01) GRANULARITY 64,
  INDEX idx_duration durationNano TYPE minmax GRANULARITY 1
) ENGINE MergeTree()
PARTITION BY toDate(timestamp)
ORDER BY (serviceName, -toUnixTimestamp(timestamp))

I don't think that is a difficult problem to solve though
